Some bifunctional heterocyclic systems having vicinal chlorocyano, chloroacetyl, and chloro-ethoxycarbonyl groups in their structures reacted with 6-amino-1,3-dimethyluracil to afford novel triheterocyclic systems having a pyrimidinedione moiety. Enaminones and α-cyanocinnamic acid derivatives in this reaction gave pyrido[2,3-d]pyrimidinediones. The antimicrobial activity of some new synthesized triheterocyclic
一些在其结构中具有邻位氯氰基,氯乙酰基和氯乙氧基羰基的双官能杂环系统与6-氨基-1,3-二甲基尿嘧啶反应,以提供具有嘧啶二酮部分的新型三杂环系统。在该反应中,烯胺酮和α-氰基氨基甲酸衍生物得到吡啶并[2,3-d]嘧啶二酮。研究了一些新合成的三杂环系统的抗菌活性。
