The first synthesis of threo and erythro (E)-4,5-dihydroxydec-2-enals, aldehydes related to the lipid peroxidation is accomplished by reaction of α-benzoyloxheptanal with the Grignard reagent of 3,3-diethoxy-1-propyne and lithium aluminum hydride reduction. Acetonization of the diol system allows a simple chromatographic separation of the diastereoisomers, the geometry of which was established by 1H
苏-和赤(E)-4,5-二羟基癸-2-烯醛(与脂质过氧化有关的醛)的首次合成是通过α-苯甲酰氧基庚醛与3,3-二乙氧基-1-丙炔的格利雅试剂和氢化铝锂还原。二醇体系的丙酮化可以简单地色谱分离非对映异构体,其几何结构通过1 H和13 C NMR实验确定,并通过(E,4R,5R)-4,5-O-的独立合成得到证实D-甘露糖醇的异亚丙基-4,5-二羟基癸-2-烯醛。
