solvent yields methyl (R)-4-succinoyloxy-5-tetradecynoate with over 90% e.e.. Furthermore, this optically active diester was converted to (R)-5-(1-decynyl)oxacyclopentan-2-one by lipase-catalyzed enantioselective lactonization which enhanced its e.e. over 99%. The Japanese beetle pheromone (R,Z)-(-)-5-(1-decenyl)oxacyclopentan-2-one is synthesized in one step from this optically active lactone.
通过在有机溶剂中脂肪酶催化的对映选择性酰化作用,可以实现4-羟基-5-十四碳烯酸甲酯的动力学拆分。在有机溶剂中将4-羟基-5-十四碳烯酸甲酯与琥珀酸酐酰化,可得到具有超过90%ee的(R)-4-琥珀酰氧基-5-十四碳烯酸甲酯。此外,该光学活性二酯通过脂肪酶催化的对映选择性内酯化作用转化为(R)-5-(1-癸炔基)氧杂环戊烷-2-酮,其ee提高了99%以上。由该光学活性内酯一步合成日本甲虫信息素(R,Z)-(-)-5-(1-癸烯基)氧环戊烷-2-酮。
