  Production of (R)-Aminoglutethimide:  A New Route from 1-Chloro-4-nitrobenzene

  摘要：

  The development of a short, safe and enantioselective route for the preparation of (R)-aminoglutethimide is described, The process was designed for economic large-scale manufacture of the bulk drug substance to acceptable quality standards, to allow clinical evaluation of the single enantiomer over the existing racemate. (R)-Aminoglutethimide was prepared from 1-chloro-4-nitrobenzene using a six-stage synthetic sequence, via chemoresolution of key intermediate racemic 4-cyano-4-(4-nitrophenyl)hexanoic acid using (-)-cinchonidine, The process allowed for preparation of several kilograms of the precursor (R)-nitroglutethimide, to cGMP at pilot-plant scale, along with demonstration of the find hydrogenation step to (R)-amino-glutethimide in the laboratory, This route avoids the problems of hazardous nitration technology, and therefore regio-isomer contamination of the product, associated with other procedures. The resolution chemistry described represents an improvement on literature procedures, Optimisation of the asymmetric Michael addition offers an attractive alternative approach.

  Using (R)- or (S)-1-phenylethylamine as a resolving agent, (R)- and (S)-4-cyano-4-(4-nitrophenyl)hexanoic acids have been isolated. Cyclization of each enantiomer, followed by reduction of the nitro group, afforded (R)- and (S)-aminoglutethimide of high (>99% ee) enantiomeric purity, respectively. The absolute configuration of (R)-(+)-3-(4-nitrophenyl)-3-ethylpiperidine-2, 6-dione was solved by X-ray single crystal analysis thus establishing the (R)-configuration of the dextrorotatory aminoglutethimide. Attempted resolution of the other precursor of aminoglutethimide, 4cyano-2-ethyl(4-nitrophenyl)butanoic acid with (S)-1-phenylethylamine led to the formation of the double salt. Its crystal structure was elucidated by X-ray crystallographic analysis. (C) 1997 Elsevier Science Ltd.
