Tin(II) enolates of thioesters are conveniently generated by the addition of stannous thiolates to ketenes. The tin(II) enolates thus formed react with aldehydes to afford the corresponding β-hydroxythioesters in a syn-selective manner. And this method is applied to an enantioselective formation of β-hydroxythioesters by the use of a chiral diamine as ligand.
硫酯的锡 (II) 烯醇化物可以通过将硫醇亚锡添加到烯酮中方便地生成。由此形成的锡 (II) 烯醇化物与醛反应以顺选择性方式提供相应的 β-羟基硫酯。并且该方法通过使用手性二胺作为配体而应用于β-羟基硫酯的对映选择性形成。
