structures of triamides 14 and diamide esters 5 and 6 are described. In crystalline form, 1, 2, and 4 adopt conformations containing an intramolecular N-H...O=C hydrogen bond in a nine-membered ring. Triamide 3 and ester diamides 5 and 6 experience only intermolecular hydrogen bonding in the solid state. We have previously concluded, on the basis of IR and 1 H NMR measurements, that triamide 1 manifests
描述了三酰胺 14 和二酰胺酯 5 和 6 的合成和晶体结构。在结晶形式中,1、2 和 4 采用在九元环中包含分子内 NH...O=C 氢键的构象。三酰胺 3 和酯二酰胺 5 和 6 在固态下仅经历分子间氢键。我们之前已经根据 IR 和 1 H NMR 测量得出结论,三酰胺 1 在二氯甲烷溶液中表现出几种不同的内部氢键模式
