An efficient synthesis of enantioenriched α-substituted γ-hydroxy esters via a kinetic resolution event is described. Bulky racemic esters in the presence of a chiral Brønsted acid selectively lactonize to yield a recoverable enantioenriched hydroxy ester and lactone. These esters are highly versatile building blocks that can readily be converted to synthetically useful materials.
描述了通过动力学拆分事件有效合成对映体富集的α-取代的γ-羟基酯的方法。在手性布朗斯台德酸的存在下,大块外消旋酯选择性地内酯化,得到可回收的对映体富集的羟基酯和内酯。这些酯是用途广泛的结构单元,可以很容易地转化为合成有用的材料。
