The present invention provides transition-metal-catalyst-based methods for the arylation and vinylation of activated methyl, methylene, and methine carbons with aryl halides, vinyl halides, and the like. The methods of the invention provide several improvements over existing methods, including the ability to synthesize efficiently and under mild conditions α-aryl and α-vinyl products from a wide range of starting materials, including ketones, esters, hydrazones, and imines. Furthermore, the methods of the invention may be used in an asymmetric sense, i.e. to produce enantiomerically-enriched chiral α-aryl and α-vinyl products.
本发明提供了基于过渡金属催化剂的方法,用于芳基卤化物、乙烯基卤化物等与活化的甲基、亚甲基和甲基碳发生芳基化和乙烯基化反应。本发明的方法相对于现有方法有几个改进之处,包括能够在温和条件下高效合成α-芳基和α-乙烯基产物,起始原料包括酮、酯、腙和亚胺等广泛范围的物质。此外,本发明的方法可以在不对称的情况下使用,即产生对映富集的手性α-芳基和α-乙烯基产物。
