DMSO-promoted direct & delta;-selective arylation of p-quinone methenylpiperidine bearinides to generate fuchsones under metal-free conditions by employing p-QMs themselves or substituted phenols as aryl sources

Fuchsones have wide applications in modern society. Present methods for generating fuchsones have many disadvantages and there are significant limitations for further exploration of fuchsone applications. Herein, we describe a DMSO-promoted direct & delta;-selective arylation of p-QMs to synthesize symmetrical and unsymmetrical fuchsones under metal-free conditions by employing p-QMs themselves or substituted phenols as aryl sources. As unprecedented methods, these novel strategies present a great advantage and significance for further exploration of fuchsones and the development of new applications.

Automated summary

Researchers have developed a novel method for synthesizing symmetrical and unsymmetrical fuchsones using p-QMs or substituted phenols as aryl sources under metal-free conditions with the promotion of DMSO. These unprecedented strategies have significant advantages and are important for further exploration of fuchsones and the development of new applications.
