Four possible isomers of 2-methyl-3, 5-dihydroxy ester derivatives, useful building blocks for natural product synthesis, were synthesized stereoselectively using C3-hydroxyl-directed methylation of β-hydroxy-δ-lactone and β, δ-dihydroxy ester.
合成了四种可能的2-甲基-3,5-二羟基酯衍生物异构体,这些异构体是自然产物合成中的有用构件,采用了以C3羟基为导向的β-羟基-δ-内酯和β,δ-二羟基酯的立体选择性甲基化方法进行合成。
