4) S-methyl lactate
S-乳酸甲酯
1.
This process began with S-methyl lactate, which was esterified with p-toluenesulfonyl chloride to give S-methyl p-toluenesulfonyl lactate, then it reacted with monoether of quinol, and at last undergone debenzylation to give methyl R-(+)-2-(4-hydtoxyphenoxy ) propionate.
因此本文报道了一种合成R-(+)-2-(4-羟基苯氧基)丙酸甲酯的新方法,以S-乳酸甲酯为起始原料,与对甲苯磺酰氯反应制备S-对甲苯磺酰乳酸甲酯。
