Stable C-glycosidic analogues of 2-O-(β-D-glucopyranosyl)-sn-glycerol (1a), 2-O-(β-D-galactopyranosyl)-sn-glycerol (1b), 1-O-(β-D-glucopyranosyl)-sn-glycerol (7) and their dipalmitoyl ester have been synthesised starting from the corresponding 2,3,4,6-tetra-O-benzyl-glyconolactones 9. The 2-O-derivatives 1 were obtained by methylenation of the lactone 9, reaction of the obtained glycoexoenitol 10 with
2-稳定C-糖苷类似物Ö - (β-d-D-吡喃葡萄糖基) - SN -甘油(1A),2- ø - (β-d吡喃半乳糖基) - SN -甘油(1B),1- ø - (β -D-吡喃葡萄糖基)-sn-甘油(7)及其二棕榈酸酯已从相应的2,3,4,6 -tetra - O-苄基-甘内酯9开始合成。通过内酯9的甲基化,所得到的糖外泌糖醇10的反应获得2- O-衍生物1。具有丙二酰基的基团,还原丙二酰基衍生物11并脱保护。通过使内酯9与丁烯基溴化镁反应,还原所获得的内酯14,进行甲磺酰化和脱保护,来获得1- O-衍生物7。©1997爱思唯尔科学有限公司。
