The synthesis of heterocyclic analogues of the platelet activating factor is described. The preparation starts with acylating rac-tetrahydro-1,3-thiazine-4-carboxylic acid ethyl ester, with palmitoyl chloride to form the amide linkage. Following ester reduction, the phosphocholine part is introduced via 2-chloro-2-oxo-1,3,2-dioxaphospholane and subsequent ring opening with trimethylamine under pressure
描述了血小板活化因子的杂环类似物的合成。制备开始于用棕榈酰氯酰化rac-四氢-1,3-噻嗪-4-羧酸乙酯,形成酰胺键。酯还原后,通过2-氯-2-氧代-1,3,2-二氧杂膦环烷引入磷胆碱部分,随后在压力下用三甲胺开环。此外,使用相同的步骤制备相关的L-噻唑烷类似物。另外,该化合物的亚磺酰基和磺酰基衍生物是通过用3-氯-过苯甲酸氧化而获得的。从一个亚磺酰基中间体中分离出非对映异构体,并通过13 C-NMR光谱确定其构象。
