Synthesis of highly diversified 1,2,3-triazole derivatives via domino [3 + 2] azide cycloaddition and denitration reaction sequence†
Abstract
In this paper, an elegant synthesis of 1,2,3-triazole derivatives via domino [3 + 2] azide cycloaddition and denitration reaction sequence under catalyst free conditions has been described. Treatment of Baylis–Hillman adducts and their cyclic derivatives from nitroolefins with sodium azide in the absence of catalyst smoothly afforded the 1,2,3-triazole derivatives in excellent yields.
