摘要

A series of homochiral cis-2-alkoxy-and 2-aryloxycyclohexanamines 5b-5e has been synthesised by means of asymmetric reductive amination of the corresponding racemic 2- oxygenated cyclohexanones 2 with ee-values ranging from 95 to> 99%. The respective 2- hydroxy and 2-cyclohexyl derivatives 5g-5h have been prepared from the 2- phenoxycyclohexanamine 4e. Relative and absolute stereochemistry has been elucidated.
