  Novel conjugates of pyridothienopyrimidinones and carbohydrates or other moieties linked by 1,2,3‐triazoles were synthesized. After establishing the pyridothienopyrimidone ring systems by ring closure, propargyl group was introduced by O‐alkylation or N‐alkylation. Cu‐catalyzed cycloaddition of the propargyl product with azido group gave the corresponding 1,2,3‐triazoles in high yields. A remarkable

  合成了吡啶并噻吩并嘧啶酮与碳水化合物或由1,2,3-三唑连接的其他部分的新型共轭物。通过闭环建立吡啶并噻吩并嘧啶酮环体系后，通过O-烷基化或N-烷基化引入炔丙基。铜催化的带有叠氮基的炔丙基产物的环加成反应可高产率地得到相应的1,2,3-三唑。观察到一个显着的情况，该反应催化环闭合以构建具有两个非对映异构体的嘧啶酮部分。对所研究的非对映异构体进行了理论计算，发现S异构体比相应的R异构体稳定约2 kcal / mol。
