preparation of phosphorus-containing heterocyclic fatty acid derivatives is described. Reaction of the C18 α-keto allene 1 and the C18 α-keto chloroallene 2 with trimethyl phosphite gave the 1,2-oxaphospholene derivatives 4 and 6, respectively. Hydrolysis of 4 and 6 furnished the corresponding alkenyl phosphonate 5 and alkenyl chlorophosphonate 7, respectively. α-Chloro-α′-keto allene 3 gave the oxaphospholene
首次成功制备含磷杂环脂肪酸衍生物。C18 α-酮基丙二烯 1 和 C18 α-酮氯丙二烯 2 与亚磷酸三甲酯的反应分别得到 1,2-氧杂磷烯衍生物 4 和 6。4 和 6 的水解分别提供了相应的烯基膦酸酯 5 和烯基氯膦酸酯 7。α-氯-α'-酮基丙二烯 3 得到氧杂磷烯衍生物 8。各种中间体和产物通过光谱和光谱技术的组合进行鉴定。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
