cyanohydrins. Among them, the cyanosilylation of carbonyl compounds using trimethylsilyl cyanide (TMSCN) is widely utilized for the synthesis of cyanohydrins. Several reagents including Lewis acids, Lewis bases, metal alkoxides, bifunctional catalysts, iodine and inorganic salts have been found to effectively transfer the cyano group from TMSCN to carbonyl compounds. Various types of Lewis acids such as AlCl3
羰基化合物的氰基甲硅烷基化是合成甲硅烷基化氰醇的有效方法,它很容易转化为几种重要的结构单元,如 α-羟基酸、α-羟基醛、1、2 二醇、α-氨基醇等。由于氰醇的重要性,人们一直将注意力集中在开发合成氰醇的实用方法上。其中,使用氰化三甲基甲硅烷(TMSCN)对羰基化合物进行氰基化反应被广泛用于合成氰醇。已经发现几种试剂,包括路易斯酸、路易斯碱、金属醇盐、双功能催化剂、碘和无机盐,可以有效地将氰基从 TMSCN 转移到羰基化合物上。各种路易斯酸如 AlCl3, 3
