A stereocontrolled synthesis of d-(+)-erythro-sphingosine (1), starting from d-xylose as chiral pool material and employing the addition-fragmentation reaction of tosyl hydrazone of 2,3 : 4,5-di-O-isopropylidene-d-xylose as key step for the chain extension with concomitant trans-selective C=C bond formation, is described.
本文介绍了一种立体可控的 d-(+)-赤藓-鞘氨醇 (1) 合成方法,该方法以 d-木糖为手性池材料,采用 2,3 : 4,5-di-O-isopropylidene-dxylose 的甲苯腙的加成-分裂反应作为链延伸的关键步骤,同时进行反式选择性 C=C 键形成。
