7-Alkyl-1, 3, 6-trimethylpyrrolo[2, 3-d]pyrimidine-2, 4(1H, 3H)-diones were readily synthesized by treatment of 6-alkylamino-5-allyl-1, 3-dimethyluracils, which were derived from 5-allyl-6-chloro-1, 3-dimethyluracil and alkylamines, with bis(acetonitrile) palladium (II) chloride. In addition, 4-alkylamino-2, 5-dimethyl-2, 3-dihydrofuro[3, 2-e]pyrimidin-6-ones were easily synthesized by treatment of 5-allyl-6-chloro-1-methyluracil with alkylamines.
7-烷基-1,3,6-三甲基吡咯并[2,3-d]嘧啶-2,4(1H,3H)-二酮可通过6-烷氨基-5-烯丙基-1,3-二甲基尿嘧啶(该化合物由5-烯丙基-6-氯-1,3-二甲基尿嘧啶和烷基胺反应得到)与双(乙腈)钯(II)氯化物的处理而容易地合成。此外,4-烷氨基-2,5-二甲基-2,3-二氢呋喃[3,2-e]嘧啶-6-酮可通过5-烯丙基-6-氯-1-甲基尿嘧啶与烷基胺的反应而容易地合成。
