D-gluco-configured building block derived from D-(+)-gluconolactone has served as a common chiral template for the synthesis of enantiopure D- and L-xylo-configured 1,2,3,4-alkane tetrols. This has enabled synthesis of medicinally important guggultetrols and their enantiomers from a common starting point. Wittig and Grignard reactions are the key steps used for the incorporation of lipophilic chain
衍生自D-(+)-葡糖酸内酯的D-葡萄糖构筑的构建基块已成为合成对映体纯D-和L-二甲苯基构筑的1,2,3,4-烷四醇的通用手性模板。从一个共同的出发点,就可以合成具有医学重要性的古吉特罗及其对映异构体。Wittig和Grignard反应是掺入亲脂性链的关键步骤。
