α-Isocyanatoacrylonitriles from alkylidene- or arylidenecyanoacetic acids; synthesis and reactions

The Curtius reaction converts alkylidene- or arylidenecyanoacetic acids to α-isocyanatoacrylonitriles in a stereospecific way. These versatile intermediates allow an easy access to arylacetic acids and various amino acid derivatives, as well as β-lactams or 2-azabutadienes.

ADDITION DE 2-ALCOXYCARBONYL AZIRIDINES YLURES D'AZOMETHINE POTENTIELS A QUELQUES VINYLISOCYANATES

The addition of azomethine ylides generated from the thermal ring opening of the corresponding 2-alcoxycarbonylaziridines on various vinylisocyanates occured exclusively on the C=N double bond.Only one orientation of the addition was observed in accordance with previous work in this area.The structure of the epimeric imidazolidones obtained was established by spectroscopic methods (RMN 1H, 13C and mass spectrometry).
