f)-cis-N-[l-(2-Hydroxy-2-phenylethyl)-3-methyl-4-piperidyll-N-phenylpropanamide (1) is a mixture of four stereoisomers [(2S, 3R, 4S)-la,(2R, 3R, 4S)-lb,(2R, 3S, 4R)-lc, and (2S, 3S, 4R)-Id], which together constitute two diastereoisomeric pairs of optical isomers. These four stereoisomers were prepared from optically active intermediates of known absolute configuration by procedures which had no effect on the configurations of the piperidine 3- ...
