presence of BF3.OEt2, affording erythro or threo β-hydroxy silanes respectively. These are, in turn, transformed into E-Z conjugated dienes of high stereoisomeric purity by acidic or basic elimination. The method serves to synthetize the pheromones of Lobesia botrana and Bombyx mori.
在BF 3 .OEt 2的存在下,顺式或反式环氧硅烷被Z-烯基铜酸盐区域性和立体选择性地打开,分别得到赤型或苏型β-羟基硅烷。然后,通过酸或碱消除将它们转化为具有高立体异构纯度的EZ共轭二烯。该方法可以用于合成柠檬茶和桑蚕的信息素。
