    Abstract: A method for preparing a compound of formula (Ia), wherein B is a purine or pyrimidine base, X is H or OH, and Y is H, OH or CH3, by (1) condensation reacting a pentose compound (II) with a protected purine or pyrimidine base B' to give a protected compound (I') in accordance with formulae (II) and (I'), wherein X' is H or OR'', where R'' is an OH function protective grouping, B' is the base B with optionally protected exocyclic functions NH2, Z is a leaving group such as a halogen or an OR group, and R and R' are OH function protective groupings; and (2) deprotecting the compound (I').

    Abstract translation: 一种制备式(Ia)化合物的方法,其中B是嘌呤或嘧啶碱基,X是H或OH,Y是H,OH或CH 3,(1)使戊糖化合物(II)与 保护的嘌呤或嘧啶碱基B',得到根据式(II)和(I')的受保护的化合物(I'),其中X'为H或OR“,其中R”为OH官能保护基, B'是具有任选受保护的环外功能NH 2的碱基B,Z是离去基团如卤素或OR基团,R和R'是OH官能保护基团; 和(2)使化合物(I')脱保护。
