The addition of TMSCN to carbonyl compounds catalyzed by K2CO3 as heterogeneous catalyst gave the corresponding cyanohydrin trimethylsilyl ethers from 20 minutes to 24 hours with 62% to 99% yields without solvent at room temperature. Moreover, it was found that chiral organic salts as heterogeneous catalysts also can catalyze the asymmetric version and afford the corresponding products with up to 99% yield and 12.4% ee.
在室温下无溶剂条件下,通过作为非均相催化剂的K2CO3催化的羰基化合物与TMSCN的加成反应,可在20分钟至24小时内以62%至99%的产率得到相应的
氰醇三甲基
硅醚。此外,研究发现手性有机盐作为非均相催化剂也能催化不对称反应,并以高达99%的产率和12.4%的ee值获得相应的产物。
