Cyclization of sulfide, ether or tertiary amine-tethered N-sulfonyl-1,2,3-triazoles: a facile synthetic protocol for 3-substituted isoquinolines or dihydroisoquinolines

Abstract

A facile synthetic method to access 3-substituted isoquinoline or dihydroisoquinoline derivatives has been developed via a novel cyclization reaction of N-sulfonyl-1,2,3-triazole derivatives by thermally induced rearrangement.
