摘要：
The development of a transition-metal-catalyzed [3 + 2] cycloaddition for one-pot synthesis of 2-substituted benzofurans from vinyl azides and benzoquinone is reported. This reaction could be carried out under mild conditions without the need to isolate air, giving desired products in good to excellent yields.
