The reaction of 4,5-diamino-1,6-dihydropyrimidin-6-ones 1 with one equivalent of the chalcones 2 leads in an acidic medium to the formation of the 2,4-diaryl-2,3,6,7-tetrahydro-1H-pyrimido[4,5-b][1,4]diazepin-6-ones 3a-m. The structure elucidation of the products is based on detailed nmr investigations including selective 13C[1H] decoupling experiments.
4,5-二氨基-1,6-二氢嘧啶-6-酮1与一当量的查耳酮2的反应导致在酸性介质中形成2,4-二芳基-2,3,6,7- tetrahydro-1 H -pyrimido [4,5- b ] [1,4] diazepin-6-ones 3a-m。产品的结构阐明是基于详细的核磁共振研究,包括选择性13 C [ 1 H]去偶联实验。
