A simple efficient, anti stereoselective, and highly regioselective method for the synthesis of β-hydroxy nitriles by the direct opening of 1,2-epoxides with KCN in acetonitrile, in the presence of metal salts, is described. This new method appears to be competitive with the other methods previously reported.
描述了一种简单有效,抗立体选择性和高度区域选择性的方法,该方法通过在金属盐存在下用乙腈中的KCN直接打开1,2-环氧化物来合成β-羟基腈。这种新方法似乎与以前报道的其他方法竞争。
