The present invention provides an efficient method for the production of N-acyl amino alcohols via the selective acylation of the free amines of amino alcohols by reacting with an organic acid or a salt thereof with an alkyl sulfonyl chloride or an alkyl phenyl sulfonyl chloride, in an organic solvent and in the presence of an organic base, to form the corresponding mixed anhydride, followed by reacting the mixed anhydride with an amino alcohol or a salt thereof to form the corresponding N-acyl amino alcohol.
本发明提供了一种高效的制备N-酰基氨基醇的方法,该方法通过将有机酸或其盐与烷基磺酰氯或烷基苯磺酰氯在有机溶剂和有机碱的存在下反应,选择性地酰化氨基醇的游离胺,形成相应的混合酐,然后将混合酐与氨基醇或其盐反应,形成相应的N-酰基氨基醇。
