Synthesis of Isoquinoline Derivatives via Ag- Catalyzed Cyclization of 2-Alkynyl Benzyl Azides

Abstract

Ag-catalyzed cyclization of 2-alkynyl benzyl azides offers a novel and efficient method for the synthesis of substituted isoquinoline. The reaction proceeds smoothly in moderate to good yields and tolerates considerable functional groups. The reaction conditions and the scope of the process are examined, and a plausible mechanism is proposed.
