New chiral diselenides were prepared in a few steps from readily available starting materials. The selenium electrophiles generated from these diselenides were used for the efficient stereoselective inter- and intramolecular functionalization of alkenes. The substitution pattern influences the stereoselectivities and protection of the hydroxy moiety in the chiral side chain led to increased selectivities
从现有的起始原料中分几步制备新的手性二硒化物。从这些二硒化物生成的硒亲电子试剂用于烯烃的高效立体选择性分子间和分子内官能化。取代模式影响手性侧链中的立体选择性和羟基部分的保护,从而导致硒基化反应中选择性和产率的提高。在第二邻位的另外的取代基也是有利的。获得具有高达96%de的加成产物。在一定程度上也研究了亲核试剂对烯烃亚硒化反应的影响。
