A cascade reaction of 2-ethynylaryl methylenecyclopropane with sulfonylazide catalyzed by copper(I) iodide under mild conditions is described, which provides a novel and efficient route for the generation of fused indolines.
synthesis of a variety of N‐containing aromatic heterocycles by a formal gold‐catalyzed dehydro‐Diels–Alder reaction of ynamide derivatives has been developed. Deuterium‐labeling experiments and kinetic studies support the involvement of a dual gold catalysis mechanism in which a gold acetylide moiety adds onto an aurated keteneiminium.
