Hydrocyanation of a range of protected β-hydroxyalkynes give unsaturated nitriles which can be cyclised to α-alkylidene γ-lactones and in most cases the regioselectivity of hydrocyanation can be controlled giving the desired cyanoalkenes with stereospecific formation of the E-isomer.
一系列受保护的β-羟基炔烃的氢氰化产生不饱和腈,其可以环化为α-亚烷基γ-内酯,并且在大多数情况下,可以控制氢氰化的区域选择性,从而得到具有立体异构的E-异构体的所需氰基烯烃。
