1,3-oxazolidines derived from tris(hydroxymethyl)aminomethane (TRIS) and pyridine-based aldehydes. Divergent results were obtained with other formylpyridines, such aspyridoxal, in which intramolecular hydrogen-bonding largely stabilizes the iminic structure. The oxazolidines may undergo ring-opening under acetylating conditions to afford imines through different mechanistic pathways, which have also
本文介绍了衍生自三(羟甲基)氨基甲烷 (TRIS) 和基于吡啶的醛的 1,3-恶唑烷的合成和结构解析。使用其他甲酰基吡啶(例如吡哆醛)获得了不同的结果,其中分子内氢键在很大程度上稳定了亚胺结构。恶唑烷可以在乙酰化条件下开环以通过不同的机制途径提供亚胺,这也已通过 DFT 计算进行评估
