catalyst has been shown to be highly effective for the hydrogenation of a wide range of α-keto esters, affording either diols or hydroxy esters depending on the choice of reaction conditions. Strong base, high temperature, and pressure favor the formation of diols whilst the opposite is true for the hydroxy esters.
钌钳状催化剂已被证明对广泛范围的α-酮酯的氢化非常有效,根据反应条件的选择提供二醇或羟基酯。强碱、高温和压力有利于二醇的形成,而羟基酯则相反。
