Synthesis of amidinoformic acids using benzyl cyanoformate as a synthon

An efficient synthesis of a variety of N-substituted or N-unsubstituted amidinoformic acids was developed starting with benzyl cyanoformate.

Carbon-carbon bond formation from ethyl cyanoformate and active methylene compounds

Abstract A new methodology which leads to α,β-unsaturated α-amino acids has been developed through a carbon-carbon forming reaction using ethyl cyanoformate and active methylene compounds in the presence of zinc chloride and triethyl amine.

Regioselective synthesis of virazole using benzyl cyanoformate as a synthon

Abstract An antiviral nucleoside or virazole was synthesized efficiently and regioselectively starting with benzyl cyanoformate.
