Subsequent mild cyclization of aromatic substrates by Pictet-Spengler condensation stereoselectively gave new tricyclic compounds. Examples are described in decent yields over two steps in one pot, and a crystal structure is also presented to support the proposed structures.
通过Pictet-Spengler 缩合反应对芳香底物进行后续温和环化,可以立体选择性地得到新的三环化合物。在一锅两步反应中以相当高的收率得到了实例,并提供了一个晶体结构来支持所提出的结构。
