Abstract
A highly efficient and convenient method for the synthesis of 6-aryl-1,2,3-triazine-4-carboxylate esters has been developed using readily accessible ( Z)-4-aryl-2,4-diazido-2-alkenoates. This reaction is performed under mildly basic conditions without the assistance of any transition metals or strong acid.
