S-炔丙醇酮化学名称为S-2-甲基-3-(2-炔丙基)-4-氧代环戊-2-烯醇，是制备右旋丙炔菊酯(商品名益多克)的重要中间体。;

其制备方法是以消旋炔丙醇酮用乙酸进行酯化，生成炔丙醇酮的乙酸酯，将其乙酸酯置于反应瓶中，加入脂肪酶(Arthrobacter或Pseudomonas脂肪酶均可)，在氮气保护下70～80℃搅拌48h，在脂肪酶作用下，R-炔丙醇酮乙酸酯易水解生成R-炔丙醇酮，而S-炔丙醇酮乙酸酯不易水解而保留乙酸酯，上述反应液加入甲苯为溶剂，并滴加甲磺酰氯或对甲苯磺酰氯，搅拌30min，R-炔丙醇酮转化为甲基磺酸酯而发生构型转位，然后用酸催化水解或用CaCO3水解，得到粗S-炔丙醇酮，为淡黄色油状物，进一步减压蒸馏得到S-炔丙醇酮。采用该方法，消旋体R，S-炔丙醇酮完全可以转变成S-炔丙醇酮。
