Abstract

Metal-Free Cycloaddition to Synthesize Naphtho[2,3-d][1,2,3]triazole-4,9-diones. -For the first time, a metal-free alcohol-azide cycloaddition is presented. The cycloaddition proceeds regioselectively. With phenol as substrate bis-triazoles are accessible. -(CHEN, P.-F.; KUO, K.-K.; VANDAVASI, J. K.; BOOMINATHAN, S. S. K.; CHEN, C.-Y.; WANG*, J.-J.; Org.
