Transition Metal-Promoted Three-Component Triene/Alkyne Cycloaddition. Facile Construction of a Novel Polycyclic Ring System

摘要

Transition metal-mediated cycloaddition has emerged as an important means for assembling ring systems that are often difficult or impossible to make in other ways. Construction of medium-sized rings through metal intervention has been a particularly fruitful area of investigation, and notable accomplishments in the preparation of seven- through tenmembered carbocycles have recently appeared.
