An efficient thioxanthone synthesis from benzoic acid esters is disclosed. Various thioxanthones were prepared by iridiumcatalyzed C-H borylation of benzoic acid esters followed by copper-catalyzed deborylthiolation and direct acid-mediated cyclization. We also achieved a synthesis of benzo-fused thioxanthones through a transformation of an aryne intermediate having an ester moiety.

Oxidative Se-catalyzed C(sp3)-H bond acyloxylation has been used to construct a diverse array of isobenzofuranones from simple ortho-allyl benzoic acid derivatives. The synthetic procedure employs mild reaction conditions and gives high chemoselectivity enabled by an inexpensive organodiselane catalyst. The presented approach offers a new synthetic pathway toward the core structures of phthalide natural products.
