D. Matecka et Br. Decosta, A STUDY OF THE EFFECT OF CATALYST ON STEREOCHEMISTRY IN THE HYDROGENATION OF NYL)-N-METHYL-2-(N-PYRROLIDINYL)-1-CYCLOHEXENAMINE, Synthetic communications, 24(11), 1994, pp. 1531-1540
Catalytic hydrogenation of nyl)-N-methyl-2-(1-pyrrolidinyl)-1-cyclohex
enamine (3) gave mainly 1R,2S-cis-N-(menthyloxycarbonyl)- and bonyl)-N
-methyl-2-(1-pyrrolidinyl)cyclohexylamines 7 and 8 with diasterostereo
selectivity favoring the 1S,2R-isomer 8.
