A Route to 1-Deoxynojirimycin and 1-Deoxymannojirimycin Derivatives with Quaternary Centers Adjacent to the Ring Nitrogen from Methyl alpha-d-Mannopyranoside

6-Alkylated-8-azido-1,6-octadiene derivatives were prepared from methyl alpha-d-mannopyranoside. The sequence to allylic azide precursors included a Horner-Wadsworth-Emmons reaction with a concomitant epimerization that ultimately enabled synthesis of 1-deoxynojirimycin as well as 1-deoxymannojirimycin derivatives. Thermally promoted allylic acid rearrangement followed by triazoline formation, then decomposition to aziridine and finally reaction with acetic acid was used to generate products that have quaternary anomeric centers adjacent to the piperidine ring nitrogen atom (cyclic alpha-tertiary amines). The stereoselectivity is accounted for based on minimization of steric interactions in the transition state structure, favoring the product where the methyl substituent is equatorial and the vinyl group prefers to be axial.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 120-73-0, in my other articles.

SUBSTITUTED CARBOXAMIDE ANALOGUES AS A NEW CLASS OF LOCAL ANESTHETIC AGENTS: SYNTHESIS AND BIO-EVALUATION

A series of N-(2-oxo-2-(phenylamino) ethyl) substituted-4-carboxamide derivatives were synthesized as local anesthetic agents. The structures of carboxamide derivatives were established on the basis of IR, and H-1 spectral data. All the compounds were subjected to surface local anesthetic activity assay and infiltration local anesthetic activity assay. Among the tested compounds, N-(2-oxo-2-(p-tolylamino) ethyl) piperidine-1-carboxamide (4h) and N-(2-((4-methoxyphenyl) amino)-2-oxoethyl) piperidine-1-carboxamide (4m) were most promising compounds in terms of surface local anaesthetic and infiltration local anaesthetic activity on rats having considerably lower liver toxicity.

Applications of tert-butanesulfinamide in the synthesis of N-heterocycles via sulfinimines

Chiral sulfinamides are among the best known chiral auxiliaries in the stereoselective synthesis of amines and their derivatives. The most extensively used enantiopure tert-butanesulfinamide emerged as the gold standard among many others over the last two decades. The present review attempts to provide an overview of tert-butanesulfinamide mediated asymmetric N-heterocycle synthesis via sulfinimines and covers literature from 2010-2020. This methodology offers general access to structurally diverse piperidines, pyrrolidines, azetidines, and their fused derivatives that represent the structural motif of many natural products and therapeutically applicable compounds.

Heterogeneous AlPO4(SO3H) nanosheets: novel catalyst for the multi-component synthesis of quinazolinones and highly functionalized piperidines

Nanosheets AlPO4(SO3H) as a highly active solid acid catalyst were prepared and characterized. The morphology of obtained catalyst exhibited nanosheets with similar to 25-35 nm thickness. The heterogeneous nanocatalyst was characterized by FT-IR, EDX, and FE-SEM analysis. The nanosulfonated-AlPO4 were found useful for cyclization synthesis of highly functionalized piperidines and quinazolinones derivatives in good to excellent yields. Notable features include easy and quick isolation of products, ease of handling of the catalyst at low cost, no need to purify with column chromatography, and mild reaction conditions. In addition, according to the literature, another significant feature of our method for quinazolinone synthesis is that structurally diverse molecules were synthesized. Finally, the newly developed catalytic systems avoid the use of toxic metal catalysts and were reused up to 5 times without a noticeable their catalytic activity.

Structure of a new usnic acid derivative from a deacylating Mannich reaction: NMR studies supported by theoretical calculations of chemical shifts

In a conventional Mannich reaction using piperidine, hydroxypiperidines, morpholine, and N-methylpiperazine with usnic acid, a deacetylation was observed resulting in a substitution at C-2, a loss of an acetyl group, and a Mannich base with a stabilized enol. The enol has a hydrogen bond to the nitrogen of the secondary amine. The structure was investigated by nuclear magnetic resonance and deuterium isotope effects on C-13 chemical shifts as well as with density functional theory calculations to study the changed hydrogen bond pattern. It was found that the hydrogen bond involving the OH-9 group in chloroform forms a strong hydrogen bond than in usnic acid itself and that this hydrogen bond becomes even stronger in the more polar solvent, dimethylsulfoxide. Tautomerism was observed in the Mannich base as demonstrated by deuterium isotope effects on chemical shifts. The position of the tautomeric equilibrium depends on the solvent, and the position of the equilibrium governs the strength of the OH-9 … O=C hydrogen bond.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 120013-39-0. The above is the message from the blog manager. Safety of 5,6-Dimethoxy-2-(4-piperidinylmethyl)-1-indanone hydrochloride.

Identification and characterization of in vitro, in vivo, and reactive metabolites of tandutinib using liquid chromatography ion trap mass spectrometry

Tandutinib (TND) is a novel, oral small molecule designed for treating acute myeloid leukemia (AML) by inhibiting type III receptor tyrosine kinases. This study reports the use of in silico, in vivo, and in vitro methods to investigate the metabolism and possible metabolic bioactivation of TND. First, in silico metabolism of TND was assessed using the WhichP450 (TM) module of the StarDrop (R) software to determine labile sites of metabolism in the TND chemical structure. Second, the XenoSite reactivity model, a web-based metabolism prediction software, was used to determine probable bioactive centers. Based on the in silico outcomes, a list of predicted metabolites and reactive intermediates were prepared. Third, in vitro and in vivo experiments were performed. In vitro TND metabolites were generated through incubation of TND with rat liver microsomes (RLMs). Another incubation of TND with RLMs was separately performed in the presence of GSH and KCN to check for the generation of reactive intermediates (soft and hard electrophiles). In vitro phase II metabolism was assessed by incubation of TND with isolated perfused rat hepatocytes. In vivo metabolism was investigated by oral gavage of TND (37 mg kg(-1)) in Sprague Dawley rats. Five in vitro phase I metabolites, one in vitro phase II and five reactive iminium intermediates (cyano adducts), six in vivo phase I, and one in vivo phase II metabolites of TND were characterized. The in vitro and in vivo metabolic pathways involved were O-dealkylation, alpha-hydroxylation, alpha-carbonyl formation, reduction, glucuronide, and sulfate conjugation. No GSH conjugate or its catabolic products were detected either in vitro or in vivo. Two cyclic tertiary rings of TND (piperazine and piperidine) were metabolically bioactivated to generate reactive iminium intermediates forming cyano adducts with KCN. The formed reactive intermediates may be the reason behind TND toxicity. In silico toxicological studies were performed for TND and its related (in vitro and in vivo) metabolites were evaluated using the DEREK software tool.

Synthesis and Investigation of Tetrahydro-beta-carboline Derivatives as Inhibitors of Plant Pathogenic Fungi

A series of tetrahydro-ss-carbolines substituted with an alkyl or acyl side chain was synthesized and screened for its antifungal activity against plant pathogenic fungi (Bipolaris oryzae, Curvularia lunata, Fusarium semitectum, and Fusarium fujikuroi). The structure activity relationship revealed that the substituent at the piperidine nitrogen plays an important role for increasing antifungal activities. In this series, 2-octyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (3g) displayed potent antifungal activities with a minimum inhibitory concentration of 0.1 mu g/mL, including good inhibitory activity to the radial growth of fungus at a concentration of 100 mu g/mL compared to amphotericin B.

Pd/PTABS: Catalyst for Room Temperature Amination of Heteroarenes

A mild and highly efficient catalytic amination procedure for chloroheteroarenes at ambient temperature using the Pd/PTABS catalytic system is reported. The protocol is selective for the amination of chloroheteroarenes using secondary amines such as piperidine, pyrrolidine, and several others.
