资源简介:
A facile one-pot method to prepare benzo[c]xanthones from readily accessible benzylidene-1-tetralones by the ultraviolet radiation-mediated tandem reaction is reported. The overall transformation presumably involves cis−trans isomerization, oxa-6π electrocyclization, singlet oxygen ene reaction, dehydration, and aromatization.
