Abstract

A novel method for the synthesis of a wide range of 1,5-disubstituted 1,2-dihydro-1,2,4-triazol-3-ones is described. The key step involves a reaction between a dilithiated BOC-hydrazine and a N-alkoxycarbonylcarboximidothioate. A broad range of aryl and alkyl functional groups are tolerated, providing a versatile route for the synthesis of triazolones.
