text] Various trisubstituted olefins were converted to configurationally stable diorganozinc compounds with high diastereoselectivity. Their reaction with various electrophiles centered on tin, sulfur, bromine, and phosphorus provided the desired substitution products with retention of configuration. Novel, functionalized organocopper reagents such as 4 and chiral diphosphine 5 have been prepared.
各种三取代的烯烃被转化为具有高非对映选择性的构型稳定的二有机锌化合物。它们与以锡,硫,溴和磷为中心的各种亲电试剂的反应提供了所需的取代产物,并且保留了构型。已经制备了新颖的,功能化的有机铜试剂,例如4和手性二膦5。
