Facile preparation of polycyclic halogen-substituted 1,2,3-triazoles by using intramolecular Huisgen cycloaddition

Abstract

1-(ω-Azidoalkyl)-2-(2,2-dihalovinyl)arenes afforded tricyclic 5-halo-1,2,3-triazoles via intramolecular Huisgen cycloaddition. Based on the remaining bromo groups, carbon elongation gave polycyclic compounds and a pentacyclic fluorescent compound.
