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.
