Disclosed are a novel 7-(N-substituted amino)-3-oxo-2-phenylheptanoate derivative of formula(2), 7-(N-substituted amino)-3-hydroxy-2-phenylheptanoate derivative of formula(3), and 7-(N-substituted amino)-3-benzenesulfonyloxy-2-phenylheptanoate derivative of formula(4), which are quite important major intermediates of an antidepressant. The 7-(N-substituted amino)-3-oxo-2-phenylheptanoate derivative can be manufactured by condensing an enolate of phenylacetates with a 5-(N-substituted amino)pentanoate derivative of formula(5).
本发明公开了一种新型的式(2)7-(N-取代氨基)-3-氧代-2-苯基庚酸酯衍生物、式(3)7-(N-取代氨基)-3-羟基-2-苯基庚酸酯衍生物和式(4)7-(N-取代氨基)-3-苯磺酰氧基-2-苯基庚酸酯衍生物,它们是抗抑郁剂相当重要的主要中间体。7-(N-取代氨基)-3-氧代-2-苯基庚酸酯衍生物可通过将苯乙酸酯的烯醇盐与式(5)的 5-(N-取代氨基)戊酸酯衍生物缩合而制得。
