Hydrolysis of substituted cyclopropane amino acids was performed. Free and partially substituted Z and E isomers of cyclopropane analogs of aspartic and adipic acids were obtained.
Cyclopropane analogs of aspartic and adipic acids were prepared by catalytic cyclopropanation of dehydro amino acid derivatives with alkyl diazoacetates in the presence of catalyst (dirhodium tetraacetate).
