The title synthesis was accomplished by featuring highly cis-selective cyclpropanation of an N-vinylcarbamate with zinc-monofluorocarbenoid followed by deprotection of the formed N-(cis-2-fluorocyclopropyl)carbamate. Optical resolution of dl-cis-2-fluorocyclopropylamine was also achieved by employing l-menthyl chloroformate as a resolving agent.

Synthetic studies on the key component of the new generation of quinolonecarboxylic acid, DU-6859. 1. Synthesis of (1R,2S)-2-fluorocyclopropylamine by the use of optical resolution
by employing highly cis-selective cyclopropanation of N-benzyl-N-vinylcarbamates with zinc-monofluorocarbenoid, deprotection of the formed N-benzyl-N-(cis-2-fluorocyclopropyl)carbamates, and opticalresolution of the resulting dl-cis-2-fluorocyclopropylamine by the use of l-menthyl chloroformate as a resolving agent. The cis-selectivity observed for the key cyclopropanation could be explained by the
