摘要
以右旋肌醇甲醚为原料,经保护的甲烷磺酸酯与腺嘌呤缩合,合成了腺嘌呤核苷类似物5。此外,化合物3经酸水解,再经环氧化高产率地合成了重要的中间体7,腺嘌呤在强有机碱存在下,对环氧化合物7进行区域性的开环反应,合成了另外两种腺嘌呤核苷类似物8和9。
Using 3-O-methyl-D-chiro-inositol as starting material, the title compound 5 was synthesized by condensation between adenine and methanesulfonate 3. Additionally, compounds 8 and 9 were prepared through the opening of epoxide ring in 7 by adenine. The key intermediate 7 was obtained in good yield via an epoxidation from mono-mesylate 6. The process of opening of epoxide ring appeared to be regioselective in presence of 1,8-diazabicyclo [ 5.4.0 ] undec-7-ene (DBU).
