An efficient route toward the synthesis of unsaturated (bis-diacetylenic) and saturated 40- and 48-membered macrocyclic biphosphocholines has been developed using 2-phenyl-5-hydroxy-1,3-dioxane as a common glycerol synthon. Ring closure was accomplished using either high-dilution Glaser oxidation of [(Cy3P)2RU==CHPh]Cl2-catalyzed olefin metathesis conditions. Deprotection of benzyl ethers using trimethylsilyl
使用2-苯基-5-羟基-1,3-二恶烷作为常见的甘油合成子,已开发出一种合成不饱和(双二乙炔)和饱和的40和48元大环双磷胆碱的有效途径。使用[(Cy3P)2RU == CHPh] Cl2-催化的烯烃复分解条件的高稀释度Glaser氧化完成闭环。还首次证明了在二乙炔基部分的存在下使用三甲基甲硅烷基碘(TMS-1)对苄基醚进行脱保护。
