The invention relates to process for the selective preparation of 3-hydroxy-6-dialkoxyphosphoryl-5-oxo-hexanoic acid esters, comprising a first step, in which a methylphosphonic acid dialkylester is treated with a base, and a second step, in which the product of the primary reaction is reacted with an optionally 3-protected 3-hydroxy-1,5-pentanoic diacid ester.
这项发明涉及一种选择性制备3-羟基-6-二烷氧基
磷酰基-
5-氧代己酸酯的方法,包括第一步,在该步骤中,
甲基膦酸二烷基酯与碱反应,以及第二步,在该步骤中,初级反应产物与可选的3-保护的3-羟基-1,5-
戊二酸酯发生反应。
