Unlike the reported reversible addition of ketone enolborinates to ketones, the aldolization of ketones with bisboron enediolates derived from carboxylic acids proceeds without difficulty. A variety of α,β,β-trisubstituted-β-hydroxy acids have been thus synthesized in good to excellent yields and diastereoselectivities.
与已报道的将酮烯醇硼酸酯可逆地添加到酮中不同,将酮与衍生自羧酸的双硼烯烯二醇酯进行的醛醇缩合没有困难地进行。因此已经以良好至优异的产率和非对映选择性合成了多种α,β,β-三取代-β-羟基酸。
