Tl. Ho et al., BEHAVIOR OF STEREOISOMERIC O-METHYLTYROSYL-P-NITROPHENYLALANINES WITHIN THE BETA-CYCLODEXTRIN CAVITY, Journal of the Chemical Society, Chemical Communications, (23), 1995, pp. 2437-2438
Cyclisation of the L,D- and L,L-O-methyltyrosyl-p-nitrophenylalanine m
ethyl esters is studied; in the presence of beta-cyclodextrin, reactio
n took place only with the L,L-isomer.
