Abstract: By condensing 1,1-dicarboxy-2-vinylcyclopropane with l-alanine methyl ester, a new chiral vinylcyclopropane derivative bearing two amide moieties 1 was synthesized. The vinylcyclopropane thus prepared was separated into two epimers, namely, RSS-1 and SSS-1. Both the epimers… read more here.
