fast and selective reduction of a deoxynucleoside N-acyl group to a corresponding N-alkyl group. Three different nucleosides (dG, dA, and dC) each having one of three N-protecting groups (benzoyl, isobutyryl, or acetyl) were used to prepare N-alkylated nucleosides in good yields under mild conditions. Deoxyribose O-acyl protecting groups remain intact at the conditions of N-acyl group reduction.
硼烷-胺络合物提供了脱氧核苷N-酰基异常快速且选择性的还原为相应的N-烷基。具有三个N-保护基团(苯甲酰基,异丁酰基或乙酰基)之一的三种不同的核苷(dG,dA和dC)用于在温和条件下以高收率制备N-烷基化的核苷。在N-酰基还原的条件下,脱氧核糖O-酰基保护基保持完整。
