A versatile synthesis of modular ascarosides, a family of signaling molecules from Caenorhabditis elegans and other nematodes, via hydrogenolysis of a cyclic sulfate derived from methyl-α-l-rhamnopyranoside is reported. The route enables selective introduction of different side chains at the 1, 2, and 4 positions of the sugar, as demonstrated for ascarosides from C. elegans and Pristionchus pacificus
据报道,通过衍生自甲基-α - 1-鼠李糖吡喃糖苷的环状硫酸盐进行氢解,可以合成一种模块化的scar虫甙,即一种来自秀丽隐杆线虫和其他线虫的信号分子家族。该路线能够在糖的1、2和4位选择性引入不同的侧链,如秀丽隐杆线虫和Pristionchus pacificus的a虫苷所证明的那样。用4'-tigloyl scar虫苷mbas#3的合成样品进行的生物测定显示出其作为回避或分散信号的作用。
