2-Benzoyl-2-ethoxycarbonylvinyl-1 and 2-benzoylamino-2-methoxy-carbonylvinyl-1 as<i>N</i>-protecting groups in peptide synthesis. Their application in the synthesis of dehydropeptide derivatives containing<i>N</i>-terminal 3-heteroarylamino-2,3-dehydroalanine
and 2-benzoylamino-2-methoxycarbonylvinyl groups in the peptide synthesis. Reactions of ethyl 2-benzoyl-3-dimethylaminopropenoate (6) with α-aminoacids gave N-(2-benzoyl-2-ethoxycarbonylvinyl-1)-α-amino acids 13–19. These were coupled with various amino acidesters to form N-(2-benzoyl-2-ethoxycar-bonylvinyl-1)-protected dipeptideesters 20–31. The removal of 2-benzoyl-2-ethoxycarbonylvinyl-1 group
