A new scheme for the synthesis of pyrrolo[2,3-d]pyrimidines from monoacetylketene animals was proposed. Reactions of monoacetylketeneN-benzoyl- andN-acetylaminals with α-bromoacetophenone afforded the corresponding 3-acetyl-2-acylamino-5-phenyl- lH-pyr-roles, which underwent cyclization to 2,4,6-trisubstituted 7Hl-pyrrolo[2,3-d]pyrimidines under the action of ammonium acetate in boiling BuOH.
提出了一种从单乙酰乙烯酮动物合成吡咯并[2,3-d]嘧啶的新方案。单乙酰烯酮N-苯甲酰基-和N-乙酰氨基与α-溴苯乙酮反应得到相应的3-乙酰基-2-酰基氨基-5-苯基-1H-吡咯,然后环化为2,4,6-三取代的7Hl-吡咯[2 ,3-d]嘧啶在醋酸铵的作用下在沸腾的 BuOH 中。
