Synthesis of (αR, 6R or 6S)-N-(α-methylbenzyl)-6-difluoromethyl-4- hydroxy-4- (4-chlorophenyl) piperidines
摘要:
Diasteroeselective synthesis of (alpha R, 6R or 6S)-N-(alpha-methylbenzyl)-6-difluoromethyl-4-hydroxy-4-(4-chlorophenyl)piperidines, which were produced from the reaction of (alpha R, 6R)- or (alpha R, 6S)-N-(alpha-methylbenzyl)-6-difluoromethyl-4-piperidone and 4-chlorophenyllithium, is described.
