three types of rearrangement reactions of sulfur ylide derived from diazoquinones and allyl/propargyl sulfides. With Rh2(esp)2 as the catalyst, diazoquinones react with allyl/propargyl sulfides to form a sulfur ylide, which undergoes a chemoselective tautomerization/[2,3]-sigmatropic rearrangement reaction, a Doyle–Kirmse rearrangement/Cope rearrangement cascade reaction, or a Doyle–Kirmse rearrangement/elimination
在这里,我们描述了重氮醌和烯丙基/炔丙基硫化物衍生的三类硫叶立德的重排反应。以Rh 2(esp)2为催化剂,重氮醌与烯丙基/炔丙基硫化物反应形成硫叶立德,并进行化学选择性互变异构/ [2,3]-σ重排反应,Doyle-Kirmse重排/ Cope重排级联反应,或Doyle-Kirmse重排/消除反应,具体取决于硫化物的取代基。该协议以中等和高收率提供了烯基和烯基硫醚以及多取代的苯酚。
