Abstract
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.
期刊介绍：
Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry.
Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters.
Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
