dehydrogenative cycloisomerization of 1,4‐enyne esters in the presence of 2,3‐dichloro‐5,6‐dicyanobenzoquinone (DDQ) or N‐fluorobenzenesulfonimide (NFSI) is described. The synthetic versatility of the methodology was exemplified by a gram‐scale reaction of one example, the ease to realize subsequent functional transformations of an adduct, and the application of the method to the synthesis of the bioactive
一种在2,3-二氯-5,6-二氰基苯并醌(DDQ)存在下依赖于连续的金(I)催化的1,4-烯炔酯的脱氢环异构化反应的合成重要的3,5-二取代苯酚衍生物的方法)或N-氟苯磺酰亚胺(NFSI)进行了描述。该方法的合成多功能性由一个实例的克级反应,易于实现加合物的后续功能转化以及将该方法应用于生物活性分子LUF5771的合成来举例说明。
