In presence of bismuth (III) chloride, a carbonylated electrophile (ethyl mesoxalate or glyoxylate) and usual diene led selectively (65 to 100%) the hetero carbonyl-Diels-Alder reaction with the ene reaction product. BiCl3 exhibits strong catalytic activity and, compared with previous literature, reacts under mild conditions.
在氯化铋(III)的存在下,羰基化的亲电试剂(中草酸乙酯或乙醛酸乙酯)和通常的二烯选择性地(65%至100%)导致杂羰基-Diels-Alder反应与烯反应产物。BiCl 3表现出很强的催化活性,并且与以前的文献相比,在温和的条件下反应。
