versatile method for efficient synthesis of a diverse range of 2-acetate substituted indoles via Rh(III)-catalyzed and alcohol-mediated C2-selective carbenoid insertion functionalization of indoles by alpha-diazotized Meldrum's acid has been developed. Furthermore, for the first time, a Rh(III)/Cu(II)-catalyzed direct C7-alkenylation of such functionalized products has also been demonstrated.
在这里,已经开发了一种新的,温和的,通用的方法,该方法可以通过α-重氮化的Meldrum酸通过Rh(III)催化和醇介导的吲哚的C2选择性类胡萝卜素插入功能化,有效合成各种范围的2-乙酸取代的吲哚。此外,还首次证明了Rh(III)/ Cu(II)催化的这种官能化产物的直接C7-烯基化。
