Novel synthetic approach to mono-O-protected anti-conformationally constrained pyrimidine acyclic nucleoside was attained from the coupling of lithiated 2,4-dimethoxy-6-methylpyrimidine with 1-benzyloxy-3-(tert-butyldiphenylsilyloxy)propan-2-one, followed by the sequential reactions of methylthiomethylation, cyclization, hydroxylation, and dealkylation.
通过将锂化的2,4-二甲氧基-6-甲基嘧啶与1-苄氧基-3-(叔丁基二苯基甲硅烷氧基)丙-2-酮偶联,获得了单-O-保护的反构象约束的嘧啶无环核苷的新颖合成方法,然后依次进行甲硫基甲基化,环化,羟基化和脱烷基化反应。
