xyloisosaccharinic acid

用法例句

The reaction of 2,3,4-tri-O-acetyl-β-D-xylopyranosyl isothiocyanate 1 and 2-amino-4/6-substituted benzothiazoles 2a～2e gave xylopyranosylthioureas 3a～3e,which then reacted with alkyl/aryl amine in the presence of HgCl_2 to afford a series of new guanidinoxylopyranosides (4a～4e,5a～5e,6a～6e and 7a～7e).

2,3,4-三-O-乙酰基-β-D-木吡喃糖基异硫氰酸酯1与2-氨基-4/6-取代-苯并噻唑2a～2e反应,生成糖基硫脲衍生物3a～3e,再在伯胺存在下经氯化汞脱硫,得到一系列新的胍基木吡喃糖苷类化合物4a～4e,5a～5e,6a～6e,7a～7e,所有新化合物的结构均经IR,~1H NMR,MS谱和元素分析证实,所得产物均为β-构型。
