摘要

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.
