Epoxidation of 3-phenoxycyclohexene 5 with m-chloro-perbenzoicacid gave 6 and 7 in a ratio of 9:1. These two epoxides were heated with a series of amines to give the aminophenoxycyclohexanol derivatives 1 and 2 respectively; in all cases the reaction was regio- and stereospecific. Two methods based on the principle of neighbouring group participation were developed to synthesize the cis-amino alcohols
