A convenient and simple method is described for formally transferring a phthaloyl protecting group from one amino group to another in an unsymmetrical diamine. The NMR spectra of some of the amido intermediates reveal that, at room temperature, there is restricted rotation around N-C=O and, in some cases, C-C=O bonds in these molecules.
本文描述了一种简便的方法,用于在不对称二胺中将邻苯二甲酰保护基从一个氨基正式转移到另一个氨基。一些氨基中间体的NMR光谱显示,在室温下,这些分子中的N-C=O和某些情况下的C-C=O键周围存在限制旋转。
