general way to synthesize 1-hydroxycycloalkene-1-carboxylic-acid derivatives from 2-(tert-butyl)-2-methyl-1,3-dioxolan-4-one (1), a chiral equivalent of glycolic acid, is reported. The method is based on a double enolate alkylation of the glycolate derivative, followed by ring closing metathesis. A formal synthesis of (−)-quinic acid is reported to demonstrate the potential of this approach.
一种从 2-(叔丁基)-2-甲基-1,3-二氧戊环-4-酮 (1)(乙醇酸的手性等价物)合成 1-羟基环烯烃-1-羧酸衍生物的特别灵活的通用方法,被报道。该方法基于乙醇酸酯衍生物的双烯醇烷基化,然后进行闭环复分解。据报道,(-)-奎尼酸的正式合成证明了这种方法的潜力。
