Article abstract of DOI:10.3987/COM-97-S80

A facile and direct method for the construction of 2′-deoxy-β-N-glycosidic linkages in 2′-deoxyribonucleoside synthesis has been developed by using 3-(3,4,5-trimethoxybenzoyl)-protected 2-deoxyribofuranosyl diethyl phosphites as a glycosyl donor in the presence of trimethylsilyl triflate, wherein coupling reactions with silylated pyrimidine bases have been found to exhibit β-selectivities up to 96%.
