Substituent Effects on 1,3-Dipolar Cycloadditions to Some 1,1-Diphenyl-2-Aza-1,3-Butadiene Derivatives.

The reactivity and in particular the siteselectivity of electrocyclic additions to 1,1-diphenyl-2-aza-1,3-butadienes, substituted or not on the terminal carbon with methyl and phenyl, and with a 3-carbomethoxyl group, have been investigated with the

New α,β-Didehydroamino Acid Derivatives as Precursors in the Synthesis of 1-Aminocyclopropanecarboxylic Acids

The reaction of N-(diphenylmethylene)didehydroalanine methyl ester and N-didehydroalanine methyl ester with diazoalkanes or ylides gives the corresponding cyclopropane derivatives in high yields.The cis/trans ratio of these compounds was dependent on substrate, reagent and reaction temperature.From stereochemically homogeneous compounds the corresponding 1-aminocyclopropanecarboxylic acids were easily obtained by acid hydrolysis.
