Asymmetric phase-transfer catalysis of homo- and heterochiral quaternary ammonium salts: development and application of conformationally flexible chiral phase-transfer catalysts

Inspired by the considerable difference of catalytic activity and stereocontrolling ability between the conformationally rigid, homo- and heterochiral quaternary ammonium bromides 1, conformationally flexible, N-spiro chiral quaternary ammonium bromides of type 4 have been designed and synthesized. Reliable procedures for the preparation of the appropriately substituted biphenyl subunits have been established by the repeated use of ortho magnesiation-halogenation as a key synthetic tool. The relationship between the structure of achiral biphenyl moiety and the reactivity and selectivity of 4 has been evaluated in the asymmetric alkylation of glycinate Schiff base 2 under typical phase-transfer conditions, leading to the identification of 4l as an optimal catalyst structure to exhibit an excellent enantiocontrol in the reactions with various alkyl halides. The molecular structure of 4l was determined by X-ray crystallographic analysis and its unique behavior in solution was examined by a variable-temperature 1H NMR study. These investigations uncovered that the observed high chiral efficiency originated from the efficient asymmetric phase-transfer catalysis of homochiral-4l, which rapidly equilibrated with heterochiral-4l of low catalytic activity and stereoselectivity.

PROCESS FOR THE PREPARATION OF ENCENICLINE FROM 7-CHLORO-BENZO[B]THIOPHENE-2-CARBOXYLIC ACID CHLORIDE AND (R)-QUINUCLIDIN-3-AMINE IN THE PRESENCE OF IMIDAZOLE

The present invention relates to a process for the preparation of an amide from a carboxylic acid chloride and an organic molecule comprising both a primary amine group and a tertiary amine group, wherein the nitrogen atom of the tertiary amine group is comprised in a non-aromatic heterocycle and wherein the amide bond forms selectively with the primary amine group, comprising the step of reacting the carboxylic acid chloride with an organic molecule comprising both the primary amine group and the tertiary amine group, in the presence of imidazole. This is particularly useful in the preparation of amides from quinuclidin-3-amine, such as for the preparation of encenicline ((R) -7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide) from 7-chloro-benzo[b]thiophene-2-carboxylic acid chloride and (R)- quinuclidin-3-amine in the presence of imidazole. Encenicline is a nicotinic acetylcholine receptor agonist useful as a neuromodulator for the treatment of e.g. cognitive impairment, schizophrenia and Alzheimer’s disease.

(R)-3?-(3-methylbenzo[6]thiophen-5-yl)spiro[1-azabicyclo[2,2,2] octane-3,5?-oxazolidin]-2?-one, a novel and potent alpha7 nicotinic acetylcholine receptor partial agonist displays cognitive enhancing properties

Recent studies have suggested that the alpha7 nicotinic acetylcholine receptors play important roles in learning and memory. Herein, we describe our research of the structure-activity relationships (SAR) in a series of (5)-spiro[1-azabicyclo[2.2.2]octane-3,5?-oxazolidin]-2?-ones bearing various bicyclic moieties to discover novel ?7 receptor agonists. Through a number of SAR studies on the series, we have found out that inhibition of CYP 2D6 isozyme, which was a primary obstacle for the previously identified compound, was avoidable by the introduction of bicyclic moieties. Chemical optimization of the series led to the identification of a novel and potent alpha7 nicotinic acetylcholine receptor partial agonist 23. This compound not only possessed high binding affinity (Ki = 3 nmol/L) toward the alpha7 receptor but also showed agonistic activity even at a concentration of 0.1 mumol/L. In addition, compound 23 improved cognition in several rat models, which might suggest the potential of the alpha7 receptor partial agonist for the treatment of neurological disorders including cognitive dysfunction.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 5-Bromobenzothiophene, you can also check out more blogs about4923-87-9
