The rhodium-catalyzed ring-opening coupling of cyclic vinyl ethers, including 2,3-dihydrofuran and benzofuran, with organometallic reagents to give homoallylic alcohols and stilbenoids was reported. The suitable organometallic reagent for 2,3-dihydrofuran and benzofuran was found to be substrate-dependent, and a plausible mechanism involving different active organorhodium intermediates was proposed
报告了铑催化的环状乙烯基醚(包括 2,3-二氢呋喃和苯并呋喃)与有机金属试剂的开环偶联,得到高烯丙醇和茋类化合物。发现适合 2,3-二氢呋喃和苯并呋喃的有机金属试剂是底物依赖性的,并且针对这些偶联反应提出了涉及不同活性有机铑中间体的合理机制。
