Nickel-Catalyzed Ring-Opening Three-Component Coupling of Methylenecyclopropane with Aldehydes and Silanes
摘要:
A nickel-catalyzed three-component coupling between methylenecyclopropane, aldehydes, and silanes afforded silylated allylic alcohols that possess an alkyl substituent at the 2-position via cleavage of the proximal C-C bond of methylenecyclopropane

sterically demanding environment. Using this newly accessible ligand class, nickel-catalyzed enantioselective reductive coupling reactions of aldehydes and alkynes have been developed. These studies illustrate that the newly available NHC ligands are well suited for simultaneous control of regio- and enantioselectivity, even in cases with internal alkynes possessing only very subtle steric differences between
