motifs involving the amino functional group. The vast variation in the hydrogen bonding motifs was found to be caused by the type of group bonded to the 4H-pyran (in Series I) or dihydropyridine (in Series II) moiety. In this work, an unprecedented hydrogen bonding motif comprising a non-classical hydrogen bond acceptor was found in one instance. For both Series I and II, the N–H···N and N–H···O hydrogen
四个 2-amino-4-(aryl)-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4 H -chromene-3-carbonitrile (系列 I ) 和三个 2-amino-1 -phenyl-7,7-dimethyl-5-oxo-4-(aryl)-1,4,5,6,7,8-hexahydroquinoline-3-carbonitrile (系列 II ) 衍生物通过多组分微波反应形成外消旋混合物. 固态 IR 光谱揭示了 3190 至 3414 cm –1区域内的谱带归因于氨基官能团的不对称、对称和弯曲泛音振动模式。此外,每个系列中一些化合物的红外光谱相似,这表明固态结构特征相似。这通过单晶 X 射线衍射得到证实。对剑桥结构数据库中相关 2-氨基-3-腈衍生物的详细调查揭示了 12 个涉及氨基官能团的经典分子间氢键基序。发现氢键基序的巨大变化是由与
