PROCESS FOR PRODUCTION OF ARALKYLOXYPYRROLIDINE DERIVATIVE
-
Page/Page column 17, (2008/12/07)
The present invention provides a process for producing a 3-aralkyloxypyrrolidine derivative which is important for production of pharmaceutical products and the like. In the present invention, a N-protected-3-hydroxypyrrolidine is converted into a N-protected-3-aralkyloxypyrrolidine by allowing an aralkyl halide to act in the presence of a base and at least one of a metal halide and a phase-transfer catalyst followed by deprotecting a N-protecting group to convert it to a 3-aralkyloxypyrrolidine derivative and subsequently treating the derivative in a solvent containing a polar solvent, thereby obtaining the 3-aralkyloxypyrrolidine derivative as a crystal. According to the present invention, a 3-aralkyloxypyrrolidine derivative of high purity can be produced conveniently and efficiently on an industrial scale.

PROCESS FOR THE PREPARATION OF CHIRAL 3-HYDROXY PYRROLIDINE COMPOUND AND DERIVATIVES THEREOF HAVING HIGH OPTICAL PURITY
-
Page/Page column 20-21, (2010/11/26)
The present invention relates to an effective process for the preparation of optically pure chiral 3-hydroxypyrrolidine or derivatives thereof. More particularly, the present invention relates to an efficient process for the preparation of chiral 3-hydroxypyrrolidine or derivatives thereof, comprised of introducing a suitable protecting group to the starting material 4-chloro-3-hydroxybutyronitrile. Introduction of the hydroxy-protecting group provides advantages: efficient prevention of formation of side products, enhanced performance of the reduction of the nitrile group of the starting material, and enhanced performance of in-situ in? tramolecular cyclization. The chiral 3-hydroxypyrrolidine compound is produced in high yield and with high purity.

STEREOSELECTIVE SYNTHESIS OF 1,2-DISUBSTITUTED CYCLOALKYLS
-
Page 22, (2010/02/04)
A stereoselectively method of preparing a 1,2-disubstituted cycloalkyl, such as aminocycloalkyl ether compounds, from a trans-1,2-disubstituted cycloalkyl or a cis-2- substituted cycloalkanol. For example, a stereoselective method of preparing 1R-(3R-hydroxypyrrolidin-1-yl)-2R-(2-phenylethoxy)-cyclohexane from 1R,2R-cyclohexanediol or from meso-cis-1,2-cyclohexanediol is described. Aminocycloalkyl ethers, such as 1R-(3R-hydroxypyrrolidin-1-yl)-2R-(2-phenylethoxy)-cyclohexane, can be used to treat cardiac disease.
Synthesis and serotonergic activity of 3-[2-(pyrrolidin-1- yl)ethyl]indoles: Potent agonists for the h5-HT(1D) receptor with high selectivity over the h5-HT(1B) receptor

The design, synthesis, and biological evaluation of a novel series of 3- [2-(pyrrolidin-1-yl)ethyl]-indoles with excellent selectivity for h5-HT(1D) (formerly 5-HT(1Dα)) receptors over h5-HT(1B) (formerly 5-HT(1Dβ)) receptors are described. Clinically effective antimigraine drugs such as Sumatriptan show little selectivity between h5-HT(1D) and h5-HT(1B) receptors. The differential expression of h5-HT(1D) and h5-HT(1B) receptors in neural and vascular tissue prompted an investigation of whether a compound selective for the h5-HT(1D) subtype would have the same clinical efficacy but with reduced side effects. The pyrrolidine 3b was initially identified as having 9-fold selectivity for h5-HT(1D) over h5-HT(1B) receptors. Substitution of the pyrrolidine ring of 3b with methylbenzylamine groups gave compounds with nanomolar affinity for the h5-HT(1D) receptor and 100-fold selectivity with respect to h5-HT(1B) receptors. Modification of the indole 5-substituent led to the oxazolidinones 24a,b with up to 163-fold selectivity for the h5-HT(1D) subtype and improved selectivity over other serotonin receptors. The compounds were shown to be full agonists by measurement of agonist-induced [35S]GTPγS binding in CHO cells expressed with h5-HT receptors. This study suggests that the h5-HT(1D) and h5-HT(1B) receptors can be differentiated by appropriate substitution of the ligand in the region which binds to the aspartate residue and reveals a large binding pocket in the h5-HT(1D) receptor domain which is absent for the h5-HT(1B) receptor. The compounds described herein will be important tools to delineate the role of h5-HT(1D) receptors in migraine.
