The one-step synthesis of 8-t-butoxycarbonyl-6,7-dimethyl-2-oxo-1,2,3,4-tetrahydropyrrolo[1,2-a]pyrimidine from acetyl methyl carbinol, 3-aminopropionic acid, and t-butyl cyanoacetate is reported. Utilizing a similar technology under basic conditions, 7-substituted 5,6-dimethyl-2-oxo-2,3-dihydro-(1H)-pyrrolo[1,2-a]imidazole is synthesized from acetyl methyl carbinol, ethyl glycinate, and the appropriate
由乙酰基甲基甲醇,3-氨基丙酸和1-氨基丁酸酯一步合成8,t-丁氧基羰基-6,7-二甲基-2-氧代-1,2,3,4-四氢吡咯并[1,2- a ]嘧啶据报道氰基乙酸叔丁酯。在碱性条件下采用类似的技术,由乙酰基甲基甲醇,甘氨酸乙酯合成7-取代的5,6-二甲基-2-氧代-2,3-二氢-(1 H)-吡咯并[1,2- a ]咪唑,以及适当的乙腈。
