Highly Diastereo- and Enantioselective Cascade Synthesis of Bicyclic Lactams in One-Pot

A versatile and highly stereoselective synthetic route to functionalized bi- and tricyclic lactams (up to > 20:1 dr and 99% ee) in one pot from simple starting materials (allylic alcohols, enals, diamines and amino alcohols) using cascade transformations promoted by chiral amine/BrOnsted or metal/chiral amine/BrOnsted relay catalysis is disclosed. Here molecular oxygen is employed as the terminal oxidant for the latter relay catalysis approach.

Directing Quinone Methide-Dependent Alkylation and Cross-Linking of Nucleic Acids with Quaternary Amines

Polyamine and polyammonium ion conjugates are often used to direct reagents to nucleic acids based on their strong electrostatic attraction to the phosphoribose backbone. Such nonspecific interactions do not typically alter the specificity of the attached reagent, but polyammonium ions dramatically redirected the specificity of a series of quinone methide precursors. Replacement of a relatively nonspecific intercalator based on acridine with a series of polyammonium ions resulted in a surprising change of DNA products. Piperidine stable adducts were generated in duplex DNA that lacked the ability to support a dynamic cross-linking observed previously with acridine conjugates. Minor reaction at guanine N7, the site of reversible reaction, was retained by a monofunctional quinone methide-polyammonium ion conjugate, but a bisfunctional analogue designed for tandem quinone methide formation modified guanine N7 in only single-stranded DNA. The resulting intrastrand cross-links were sufficiently dynamic to rearrange to interstrand cross-links. However, no further transfer of adducts was observed in duplex DNA. An alternative design that spatially and temporally decoupled the two quinone methide equivalents neither restored the dynamic reaction nor cross-linked DNA efficiently. While di- and triammonium ion conjugates successfully enhanced the yields of cross-linking by a bisquinone methide relative to a monoammonium equivalent, alternative ligands will be necessary to facilitate the migration of cross-linking and its potential application to disrupt DNA repair.

Asymmetric Organocatalytic Synthesis of Bisindoles – Scope and Derivatizations

Starting from 3-vinylindoles and glyoxolate imines, we created a library of diverse 4,6-bis(1H-indole-3-yl)piperidine 2-carboxylates by using 10 mol-% of a chiral phosphoric acid. Utilising electron-withdrawing groups on the starting material during the reaction led to the formation of Povarov-type structures, which extended the previous library of molecules. Furthermore, we could demonstrate that consecutive reactions like reductions, cross coupling reactions or click reactions on bisindoles are feasible.

Efficient synthesis of aurone Mannich bases and evaluation of their antineoplastic activity in PC-3 prostate cancer cells

An efficient method for regioselective synthesis of C-7 Mannich bases of 6-hydroxyaurones was accomplished by the N,N-dialkylaminomethylation using aminals prepared from dimethylamine, dipropylamine, bis(2-methoxyethyl)amine, N-methylbutylamine, N-methylbenzylamine, morpholine, piperidine, and 1-methylpiperazine. Further transformation of 7-(N,N-dialkylamino)methyl group in these aurones led to formation of C-7 acetoxymethyl and methoxymethyl derivatives of 6-hydroxyaurones, some of which showed promising inhibition of PC-3 prostate cancer cell proliferation in the high nanomolar to low micromolar range that exceeded that of cisplatin. Compound 12c (R-3 = Ac, Ar = 3,4-OMePh) displays 75% inhibition of PC-3 prostate cancer cells proliferation at 300 nM concentration. [GRAPHICS] .

Tf2O-Promoted Intramolecular Schmidt Reaction of the omega-Azido Carboxylic Acids

A designed Tf2O-promoted intramolecular Schmidt reaction of 2-substituted omega-azido carboxylic acids was demonstrated. Tf2O was used as an activation reagent for the carboxylic acid, and omega-azido anhydride was in situ generated, releasing a molecular TfOH, which acted as an acid promoter for the Schmidt process. A series of 2-substituted pyrrolidines was produced and acetylated for better purification. The strategy was also efficient for conversion of a 4-substituted omega-azido carboxylic acid to the tricyclic lactam.

Identification and quantification of five impurities in cloperastine hydrochloride

Cloperastine hydrochloride, a piperidine derivative, is a drug substance with a central antitussive effect and widely used in cough treatment; and its impurities have not been reported. Herein we isolated and identified five impurities (named as impurity A, B, C, D and E) in cloperastine hydrochloride bulk drug and developed a quantitative HPLC method. First, impurity A, B, C were enriched by ODS column chromatography and isolated by semi-preparative HPLC, at the same time, impurity D was purified by ODS column chromatography. Then, impurity E was enriched by strong acid degradation and purified by semi-preparative HPLC. At last, their structures were characterized by a variety of spectral data (MS, H-1 NMR, C-13 NMR, HSQC, HMBC and H-1-H-1 COSY). Impurity A was confirmed as 1-[2-(diphenylmethoxy)ethyl]piperidine, which having one less chloro-substituent compared with cloperastine. Impurity B was confirmed as 1-[2-[(2-chlorophenyl)(phenyl)methoxy]ethyl]piperidine, which was the isomer of cloperastine with 2-chloro-substituent. Impurity C was confirmed as 1-[2-[(3-chlorophenyl)(phenyl)methoxy]ethyl]piperidine, which was the isomer of cloperastine with 3-chloro-substituent. Impurity D was confirmed as (4-chlorophenyl)(phenyl)methanone, which was the raw material for the synthesis of cloperastine. Impurity E was confirmed as (4chlorophenyl)(phenyl)methanol, which was an intermediate in the synthesis of cloperastine, and it was also a hydrolysate of cloperastine. Finally, the developed method was validated in terms of specificity, linearity, sensitivity, precision and accuracy. (C) 2020 Published by Elsevier B.V.
