An efficient and convenient synthetic route to glycosyl 1-β-phosphates has been developed using diallyl chlorophosphate as a phosphorylating agent with 4-N,N-dimethylaminopyridine under mild conditions. Diallyl-glycosyl 1-β-phosphate triesters of d-manno, l-glycero-d-manno-hepto-, d-gluco-, d-galacto-, and l-fuco-pyranose as well as lactose have been obtained by this strategy in good yields and excellent
已经开发了使用二烯丙基氯磷酸酯作为磷酸化剂与4- N,N-二甲基氨基吡啶在温和条件下的合成糖基1-β-磷酸的有效且方便的途径。的二烯丙基糖基1-β-磷酸三酯d -manno,升-甘油基- d -甘露-hepto-,d -gluco-,d -galacto-,和升-fuco吡喃糖以及乳糖已经通过此获得的高收率和出色的β选择性的最佳策略。此外,二烯丙基6-叠氮基-甘露糖基1-β-磷酸酯2在温和的条件下脱保护,并转化为可能的可点击的β-甘露糖基磷酸异戊二烯I和ADP-庚糖II类似物。
