M. Kirihara et al., Synthesis of (+)-(R)-1-amino-2,2-difluorocyclopropane-1-carboxylic acid through lipase-catalyzed asymmetric acetylation, CHEM LETT, (5), 1999, pp. 405-406
(+)-(R)-1-Amino-2,2-difluorocyclopropane-1-carboxylic acid was synthesized
via the lipase-catalyzed asymmetric acetylation of a pro-chiral diol as the
key step.
