reaction of benzofuran-2,3-dione derivatives 1 with CO and alkenes (or alkynes) results in a carbonylative [2+2+1] cycloaddition in which the ester-carbonyl group is incorporated into a two-atom assembling unit to give spirolactone derivatives 2. This reaction provides the first example of an ester-carbonyl group participating in a carbonylative cycloaddition reaction.
苯并呋喃-2,3-二酮衍生物1与一氧化碳和烯烃(或炔烃)的反应导致羰基化[2 + 2 + 1]环加成反应,其中酯-羰基被掺入两个原子的组装单元中,从而得到螺内酯衍生物2。该反应提供了参与羰基化环加成反应的酯-羰基的第一个例子。
