Abstract

Abstract Diazomethane transforms N-(phenylthio-carbonyl)-amino acid esters or amides into the corresponding N-carbonyl derivatives, similarly it converts N-(phenylthio-carbonyl)-butyl- 1-amine into butyl-isocyanate. Solvents with a high dielectric constant (eg nitromethane, ethanol) favour this transformation. The analogous but N-substituted N-(phenyloxy-carbonyl)- amino acid esters are not modified by diazomethane. This new reaction appears to ...
