摘要

本文介绍了尝试采用不同方法将 9,10-二芳基苯并[h]喹啉和 9,10-二(杂)芳基菲烷分子内环化为具有扩展对偶共轭体系的芳烃。起始化合物(9,10-二芳基苯并[h]喹啉和 9,10-二(杂)芳基菲)是通过在 1- 氮杂联苯或联苯中活化 C-C 键,然后插入内部炔烃制备的。有趣的是,与纯碳基芳烃不同,环化过程在很大程度上取决于母体化合物的结构。在少数情况下,得到了预期或理想的产物。在其他情况下,基本分子框架会发生意想不到的重排。

Biphenylene and 1‐Azabiphenylene as a Platform for Synthesis of Azapolyaromatic Compounds

Attempts to carry out intramolecular annulation of 9,10‐diarylbenzo[h]quinolines and 9,10‐di(hetero)arylphenanthrenes to aromatics with expanded π‐conjugated systems by using different methods are described. The starting compounds (9,10‐diarylbenzo[h]quinolines and 9,10‐di(hetero)arylphenanthrenes) were prepared by C−C bond activation in 1‐azabiphenylene or biphenylene followed by insertion of internal alkynes. Interestingly, unlike in purely carbon‐based aromatics, the course of the annulation turned out to be highly dependent on the structure of maternal compounds. In a handful of cases were obtained the expected or desired products. In others, unexpected rearrangements of the basic molecular frameworks were observed.

期刊介绍: Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC) The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
