Transformation of 5-acylated N-fluoroalkyl-1,2,3-triazoles to trifluoromethylated ring-fused isoquinolines, 1,3-oxazines, and 1,3-oxazin-6-ones via ketenimines

Abstract

A new synthetic approach towards trifluoromethylated heterocycles, based on the reaction of 5-acylated N-fluoroalkyl substituted 1,2,3-triazoles under microwave heating, proceeding via ketenimines is presented.
