Cj. Easton et al., HIGH ENANTIOSELECTIVITY IN THE REACTIONS OF (R)-AND (S)-1-PHENYLETHYLAMINE WITH 6(A)-DEOXY-6(A)-IODO-BETA-CYCLODEXTRIN, Journal of the Chemical Society, Chemical Communications, (11), 1995, pp. 1167-1168
6(A)-Deoxy-6(A)-iodo-beta-cyclodextrin reacts with (R)-1-phenytethylam
ine one hundred and sixty times faster than it reacts with the corresp
onding (S)-enantiomer of the amine.
