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。
The first synthesis of the four possible isomers of (E)-4,5-dihydroxydec-2-enal, a cytotoxic product of microsomal lipid peroxidation, is accomplished starting with D- and L-arabinose, D-ribose and D-lyxose by an identical reaction sequence. Each pentose was diacetonised and subjected to a Wittig reaction for the introduction of a four carbon chain. A selective cleavage of the terminal isopropylidene acetal and the oxidation of the diolic system affords a noraldehyde which is treated with (formylmethylene)triphenylphosphorane to afford the target molecule after regeneration of the diolic system.
