Abstract

A facile and efficient protocol for Ir(III)-catalyzed ortho-alkenylation and annulation of N-iminopyridinium ylides with acrylates and alkynes has been developed, providing o-alkenyl benzamides and isoquinolones in good to excellent yields. This reaction proceeds well under external oxidant free conditions with high practicality and efficiency, and broad functional group tolerance.

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.
