Abstract

A tandem oxidative cyclization/1,2-carbon migration of a broad scope of hydrazides enables the synthesis of otherwise inaccessible hindered or enantiopure triazolopyridinones with retention of configuration. This protocol can be easily scaled up by continuous flow synthesis under mild conditions.
