A simple, one-pot preparation of cyclic amines via efficient chlorination of amino alcohols with use of SOCl2 has been developed. This approach obviates the need for the classical N-protection/O-activation/cyclization/deprotection sequence commonly employed for this type of transformation. The reaction pathways and the general scope of this method have also been investigated.
已经开发出一种简单的一锅法,通过使用SOCl 2对氨基醇进行有效氯化来制备环胺。该方法消除了通常用于这种类型的转化的经典的N-保护/ O-活化/环化/去保护序列的需要。还研究了该方法的反应途径和一般范围。
