asymmetric epoxidation of 3-cyanoallyl alcohol (4-hydroxy-2-butenecarbonitrile, 6) afforded a potentially useful chiral building block, 3-cyano-2,3-epoxypropan-1-ol (7). Kinetic resolution of the secondary γ-cyano allylic alcohol (rac-3) provided an efficient method for synthesis of optically active 3. The Epoxidation of optically active 3 to γ-cyano-α,β-epoxy alcohol 5 was also reported.
3-氰基烯丙基醇(4-羟基-2-丁烯腈,6)的Sharpless不对称环氧化提供了一种潜在有用的手性结构单元,3-cyano-2,3-epoxypropan-1-ol(7)。仲γ-氰基烯丙基醇(rac-3)的动力学拆分为合成旋光活性3提供了一种有效的方法。还报道了旋光性化合物3被环氧化为γ-氰基-α,β-环氧醇5。
