Aromatic metamorphosis: conversion of an aromatic skeleton into a different ring system

摘要: Aromatic skeletons are generally regarded as being uncleavable because of their aromatic stabilization energy. Compared to exocyclic functionalizations compounds, much less attention has been paid substitutions endocyclic atoms in cores through partial disassembly the cyclic and subsequent ring reconstruction. In this Feature Article, we describe our endeavours establish “aromatic metamorphosis”, where general compounds such dibenzothiophenes, dibenzofurans, benzofurans transformed into different systems using a multi-step strategy or ideally one step.
