A general procedure has been developed for the preparetion of 9-alkylated adenines by the Mitsunobu reaction between 6-chloropurine and several alcohols, followed by the replacement of the chlorine with ammonia. A lesser amount of the 7-alkylpurines was also obtained, irrespective of the alcohol used.
通过 6-氯嘌呤与几种醇之间的 Mitsunobu 反应,然后用氨取代氯,制备 9-烷基腺嘌呤的一般程序已经开发出来。无论使用哪种醇,都能得到较少量的 7-烷基嘌呤。
