A boron-catalyzed Michael reaction using pairs of carboxylic acids was developed. The reaction occurs through dual activation of the two substrates by a boron catalyst, which facilitates boron enolate formation from the donor carboxylic acid with simultaneous activation of the α,β-unsaturated carboxylic acid as the acceptor. α-Aryl and α-alkenyl carboxylic acids were applicable as donors. The versatility
开发了使用成对羧酸的硼催化迈克尔反应。该反应通过硼催化剂对两种底物的双重活化而发生,这促进了供体羧酸形成硼烯醇化物,同时活化作为受体的α,β-不饱和羧酸。 α-芳基和α-烯基羧酸可用作供体。通过直接使用药物作为供体羧酸证明了该反应的多功能性和实用性。
