Reductive cyclisation of 2-azidophenyl esters to 2-substituted benzoxazoles

Abstract

Triethyl phosphite reacts with o-azidophenyl esters to give 2-substituted benzoxazoles via phosphorimidate intermediates, but a comparison with the corresponding reaction of o-nitrophenyl esters suggests different mechanisms for these two reactions.
