2-iminothiazolidin-4-ones using LiAlH4 at room temperature. Due to the presence of the restricted rotation around the N3-Caryl single bond, the formation of M/P isomers was observed. The OH group of the hemiaminal was found to orient itself on the same side with pyridyl nitrogen during this restricted rotation to form an intramolecular hydrogen bond, which was demonstrated by the computational DFT study. This orientation
在这项研究中,我们在室温下使用 LiAlH 4从 2-iminothiazolidin-4-ones 区域选择性地合成了一系列 3-(pyridin-2-yl)-2-(pyridin-2-ylimino)thiazolidin-4-ol 衍生物. 由于围绕 N3-C芳基单键旋转受限,观察到 M/P 异构体的形成。发现半缩醛胺的 OH 基团在这种受限旋转过程中与吡啶基氮位于同一侧以形成分子内氢键,计算 DFT 研究证明了这一点。这种取向可能会抑制脱水的发生并稳定分子。
