synthesis of purines bearing functionalized carbon substituents or methyl in position 6 was developed. Under different reaction conditions, 6-halopurine derivatives could react with ethyl acetoacetate efficiently to yield 2-(purin-6-yl)acetoacetic acid ethyl esters, (purin-6-yl)acetates and 6-methylpurines respectively. No metal catalyst and ligand were required.
开发了一种新颖的合成嘌呤的新方法,该嘌呤在6位带有官能化的碳取代基或甲基。在不同的反应条件下,6-卤代嘌呤衍生物可与乙酰乙酸乙酯有效反应,分别生成2-(嘌呤-6-基)乙酰乙酸乙酯,(嘌呤-6-基)乙酸酯和6-甲基嘌呤。不需要金属催化剂和配体。
