【摘要】 2′-O-对甲苯磺酰基-c-AMP以对甲苯磺酰氯或三苯基膦/四氯化碳作缩合剂,与不同醇或胺反座得到3′,5′-环核苷酸磷酸酯或磷酰胺,以上他合物在乙二醇二甲醚中于-60°用茶化钠或蒽化钠反应可以脱去对甲苯磺酰基,同时分离了这些磷酸酯或磷酰胺的立体异构体。更多还原

【Abstract】 By using tosyl chloride or triphenyl phosphine/carbon tetrachloride as condensing reagents, 2’-tosyl c-AMP reacted with ROH or RNH2 to give nucleoside 3’,5’-cyclic phosphotri-esters and phosphoramidates in 30-60% yield. Detosylation was carried out by using sodium naphthaline at -60℃+ in DME in 70-90% yield. The stereoisomers of these compounds have been separated and the structures have been identified by 1H NMR, 13C NMR, 31P NMR and FDMS.更多还原
