This paper reports a new method for synthesizing an acyclic version of 6 '-methylene and 6 '(alpha)-methylated carbovir analogues. The introduction of a methylene group to the requisite 6 '-position was carried out employing a Mannich type reaction using Eshenmoser's salt (methylene-N,N-dimethylammonium iodide). Carbonyl enolate alkylation (LiHMDS, CH3I) was used to introduce a methyl group to the
本文报道了一种合成6'-亚甲基和6'-α-甲基化Carbovir类似物的无环版本的新方法。使用曼尼希型反应,使用艾氏莫司氏盐(亚甲基-N,N-二甲基碘化铵),将亚甲基引入所需的6'-位。烯醇羰基烷基化(LiHMDS,CH 3)用于将甲基引入6'α-位。通过SN2型反应和脱保护,从溴化物化合物8和14成功地合成了鸟嘌呤类似物。当对合成的化合物11和17进行HIV-1测试时,它们显示出与任何抗HIV活性无关的毒性。
