Synthetic receptors (H3, H4, H5 and H6) are designed and synthesised for the first time for theobromine, a xanthine alkaloid used as a diuretic. The synthesis of the receptor H6 is achieved by Co(PPh3)3Cl-mediated homocoupling of 3-(ethoxycarbonyl)benzyl bromide 12 under mild conditions. New caffeine receptors (H7, H8 and H9) are designed and synthesised. The binding results of theobromine and caffeine (both by NMR and UV studies) are reported.
首次设计并合成了可可碱的合成受体(H3、H4、H5 和 H6),可可碱是一种用作利尿剂的黄嘌呤生物碱。受体 H6 是在温和条件下通过 Co(PPh3)3Cl 介导的 3-(乙氧基羰基)苄基溴 12 的同偶联反应合成的。设计并合成了新的咖啡因受体(H7、H8 和 H9)。报告了可可碱和咖啡因的结合结果(通过核磁共振和紫外线研究)。
