the basis of isosteviol, d-arabinofuranose, and d-ribofuranose. In the first stage, isosteviol reacted with methyl 5-O-(p-tosyl)-2,3-di-O-benzoyl-d-ribofuranoside and methyl 5-O-(p-tosyl)-2,3-di-O-benzoyl-d-arabinofuranoside to give glycoconjugates in which the diterpenoid fragment is linked through ester bond to the carbohydrate C5 atom. In the second stage, the anomeric methoxy group in the furanoside
在异osteviol ,d-阿拉伯呋喃糖和d-呋喃核糖的基础上,在三个阶段中合成了首个磷酸化的糖缀合物。在第一阶段,异反应用甲基-5- ø - (p甲苯磺酰基)-2,3-二- ö -benzoyl- d -ribofuranoside和5- ø - (p甲苯磺酰基)-2,3-二ø -benzoyl- d -arabinofuranoside,得到糖结合物,其中所述二萜片段是通过酯键与碳水化合物C连接的5原子。在第二阶段中,呋喃糖苷片段中的异头甲氧基被溴取代,生成的2,3-di -O-benzoyl- d呋喃核糖基和2,3-二-O -benzoyl- d -arabinofuranosyl溴化物用磷酸二丁酯,得到目标磷酸化衍生物处理。
