A new efficient synthesis of 1-aminocydopropanecarboxylic acid (ACC) from methyl 2-diphenylmethyleneaminoacrylate in nearly quantitative yield has been developed. The key step in the synthesis is the removal of both protecting groups in mild conditions and in quantitative yield to afford ACC.

The reactivity and in particular the siteselectivity of [3+2] 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 1,3-dipolar reagents 4-nitrobenzonitrile oxide and diazomethane. The role of the 3-carbomethoxy substituent in determining the siteselectivity observed in these reactions is discussed in relation to experimental results and to conformational models of some of the tested 2-azadiene dipolarophiles calculated on AM1 bases.

idehydroalanine 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-aminocyclopropanecarboxylicacids were easily obtained by acid hydrolysis.
