Ni-Catalyzed Intramolecular Cycloaddition of Methylenecyclopropanes to Alkynes
摘要:
Ni-catalyzed intramolecular cycloaddition of methylenecyclopropanes (MCPs) to arkylalkynes via proximal bond cleavage is reported. The reaction provides a facile route for the preparation of cyclopenta[a]indene derivatives.
