1 H NMR and IR studies of triamide 1 and related compounds indicate that 1 undergoes dramatic temperature-dependent conformational changes in relatively nonpolar solvents (methylene chloride and chloroform). The foldingpattern favored at low temperatures in these chlorocarbons (1c) contains a single C=O---H-N hydrogen bond in a nine-membered ring, while a foldingpattern containing only a six-membered-ring
三酰胺 1 和相关化合物的变温 1 H NMR 和 IR 研究表明,1 在相对非极性的溶剂(二氯甲烷和氯仿)中会发生显着的温度依赖性构象变化。这些氯烃 (1c) 在低温下的折叠模式在九元环中包含单个 C=O---HN 氢键,而折叠模式仅包含一个六元环 C=O--- NH 相互作用(1a)在较高温度下是有利的。二甲基亚砜是一种非常强的氢键接受溶剂,会破坏 1 中的所有内部氢键。乙腈似乎可以选择性地破坏六元环氢键,并在室温下促进九元环相互作用,相对于氯烃而言溶剂

In connection with our studies to develop an assay method for 4-chloro-2-(o-chlorobenzoyl)-N-methyl-Nα-glycylglycinanilide (1), a colored substance formed by the reaction of 1 with the reagent 3, 5-dibromosalicylaldehyde (DBSA) was isolated and its chemical structure was investigated. Another colored substance formed by the same reaction of glycinemonomethylamide (3) with DBSA was also isolated, and the chromophoric structure was shown to be essentially the same as that of the compound formed in the reaction of 1 with DBSA. On the basis of spectrometric and chemical evidence, the colored compounds were determined to be N-substituted 5-(3, 5-dibromo-2-hydroxybenzylidene)-2-(3, 5-dibromo-2-hydroxyphenyl)-1-imidazoline-4-ones. The reaction mechanism of the coloration in the assay of 1 is discussed.
regioselective synthesis of 3-aminoimidazo[1,2-a]pyrimidines via triflic anhydride mediated amide activation and intramolecular cyclisation is reported. The nature of the added pyridine base allows access to both regioisomers from a simple common precursor. The method tolerates a range of functional groups and provides access to novel heterocyclic scaffolds. The regioselective synthesis of 3-aminoimidazo[1
