Copper-ligand clusters dictate size of cyclized peptide formed during alkyne-azide cycloaddition on solid support

Peptide and peptidomimetic cyclization by copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction have been used to mimic disulfide bonds, alpha helices, amide bonds, and for one-bead-one-compound (OBOC) library development. A limited number of solid-supported CuAAC cyclization methods resulting in monomeric cyclic peptide formation have been reported for specific peptide sequences, but there exists no general study on monocyclic peptide formation using CuAAC cyclization. Since several cyclic peptides identified from an OBOC CuAAC cyclized library has been shown to have important biological applications, we discuss here an efficient method of alkyne-azide ‘click’ catalyzed monomeric cyclic peptide formation on a solid support. The reason behind the efficiency of the method is explored. CuAAC cyclization of a peptide sequence with azidolysine and propargylglycine is performed under various reaction conditions, with different catalysts, in the presence or absence of an organic base. The results indicate that piperidine plays a critical role in the reaction yield and monomeric cycle formation by coordinating to Cu and forming Cu-ligand clusters. A previously synthesized copper compound containing piperidine, [Cu4I4(pip)(4)], is found to catalyze the CuAAC cyclization of monomeric peptide effectively. The use of 1.5 equivalents of CuI and the use of DMF as solvent is found to give optimal CuAAC cyclized monomer yields. The effect of the peptide sequence and peptide length on monomer formation are also investigated by varying either parameter systemically. Peptide length is identified as the determining factor for whether the monomeric or dimeric cyclic peptide is the major product. For peptides with six, seven, or eight amino acids, the monomer is the major product from CuAAC cyclization. Longer and shorter peptides on cyclization show less monomer formation. CuAAC peptide cyclization of non-optimal peptide lengths such as pentamers is affected significantly by the amino acid sequence and give lower yields.

Thermal decomposition investigation of paroxetine and sertraline

Antidepressants paroxetine and sertraline both as their hydrochlorides were studied regarding thermal behavior by TG/DTG-DTA, DSC, hot-stage microscopy, X-ray diffraction and coupled TG-FTIR. Paroxetine presented a single mass loss step after dehydration, in nitrogen. However, DTA curve revealed that such degradation actually occurs in three steps, in which HCl, piperidine, fluorobenzene and CO2 are released. In air decomposition took place in a similar way. DSC showed endothermic peaks related to melting and dehydration of paroxetine. During evolved gases analysis it was possible to observe overlapped signals related to HCl and piperidine absorption. Sertraline, on its turn, presented sublimation when slowly heated or alternatively a solid transition from Form II to Form III at c.a. 199 degrees C followed by two mass losses when heated at higher heating rates. In the first degradation step methylamine is released. The second step is related to the loss of tetraline, dichlorobenzene and HCl, as revealed by TG-FTIR. Based on these data, thermal decomposition mechanisms were proposed for both drugs.

Catalytic Asymmetric Aza-Diels-Alder Reaction: Pivotal Milestones and Recent Applications to Synthesis of Nitrogen-Containing Heterocycles

In this review, the pivotal achievements and recent advances in catalytic asymmetric aza-DAR reported up to 2020 are retrospectively considered and their potency for enantioselective synthesis of useful chiral piperidine, quinoline, pyridazine, oxazine and oxadiazine derivatives and fused compounds of higher molecular complexity bearing these pharmacology-relevant heterocyclic scaffolds is demonstrated. The reported data are systematized according both to key electron transfer modes (normal or invers electron demand reactions) and to main types of attainable heterocyclic products. Of significant attention are an analysis of activation strategies (complexation, enamine or enolate formation, H-bonding, etc.) applicable to reactions with particular types of dienes and dienophiles and identification of plausible reaction pathways (either concerted or stepwise) over stereoselective cyclization processes. The review contains 310 references and 122 synthetic schemes.

Stereoselective synthesis of 2,6-trans-4-oxopiperidines using an acid-mediated 6-endo-trig cyclisation

An acid-mediated 6-endo-trig cyclisation of amine-substituted enones has been developed for the stereoselective synthesis of trans-6-alkyl-2-methyl-4-oxopiperidines. Performed under conditions that prevent removal of the Boc-protecting group or acetal formation, the key cyclisation was found to generate cleanly the 4-oxopiperidine products in high overall yields from a wide range of alkyl substituted enones. The synthetic utility of the trans-6-alkyl-2-methyl-4-oxopiperidines formed from this process was demonstrated with the total synthesis of the quinolizidine alkaloid, (+)-myrtine and the piperidine alkaloid, (-)-solenopsin A.

Hierarchical ZSM-5 zeolite with radial mesopores: Preparation, formation mechanism and application for benzene alkylation

Hierarchical ZSM-5 zeolite with radial mesopores is controllably synthesized using piperidine in a NaOH solution. The piperidine molecules enter the zeolite micropores and protect the zeolite framework from extensive desilication. The areas containing fewer aluminum atoms contain fewer piperidine protectant molecules and so they dissolve first. Small amounts of mesopores are then gradually generated in areas with more aluminum atoms and more piperidine protectant. In this manner, radial mesopores are formed in the ZSM-5 zeolite with a maximal preservation of the micropores and active sites. The optimal hierarchical ZSM-5 zeolite, prepared with a molar ratio of piperidine to zeolite of 0.03, had a mesopore surface area of 136 m(2)center dot g(-1) and a solid yield of 80%. The incorporation of the radial mesopores results in micropores that are interconnected which shortened the average diffusion path length. Compared to the parent zeolite, the hierarchical ZSM-5 zeolite possesses more accessible acid sites and has a higher catalytic activity and a longer lifetime for the alkylation of benzene.

Ring opening of 2,6-diaryl-3,5-diphenyl piperidine-4-one by acetic acid: Structural studies and Hirshfeld surface analysis of (E)-4-aryl-1,3-diphenylbut-3-en-2-ones

Six alpha,beta-unsaturated carbonyl compounds have been obtained from 2,6-diaryl-3,5-diphenylpiperidine-4-one by the treatment with acetic acid. A plausible mechanism for the ring opening of 2,6-diaryl-3,5-diphenyl piperidin-4-ones is proposed. The resultant (E)-4-aryl-1,3-diphenylbut-3-en-2-ones have been characterized by H-1 and C-13 nuclear magnetic resonance (NMR) spectral studies. One of the compounds was completely characterized by 2D NMR techniques, and structure of the compound is further proved by single-crystal X-ray diffraction (XRD) analysis. The crystal structure, three-dimensional framework of crystal, and Hirshfeld surface analysis of two of the compounds have been discussed. In the crystals, molecules are mainly linked by C-H center dot center dot center dot O hydrogen bonding interactions, and this interaction forms an inversion dimer with R-2(1)(6) and R-2(1)(10) ring motifs in one of the compounds. Hirshfeld surface indicates the dominance of H center dot center dot center dot H contacts on the overall surface.

Deconstructive fluorination of cyclic amines by carbon-carbon cleavage

Deconstructive functionalizations involving scission of carbon-carbon double bonds are well established. In contrast, unstrained C(sp(3))-C(sp(3)) bond cleavage and functionalization have less precedent. Here we report the use of deconstructive fluorination to access mono-and difluorinated amine derivatives by C(sp(3))-C(sp(3)) bond cleavage in saturated nitrogen heterocycles such as piperidines and pyrrolidines. Silver-mediated ring-opening fluorination using Selectfluor highlights a strategy for cyclic amine functionalization and late-stage skeletal diversification, establishing cyclic amines as synthons for amino alkyl radicals and providing synthetic routes to valuable building blocks.
