DTBP-mediated controlled oxidative C-S bond cleavage/annulation cascade: construction of indenones

A novel controlled DTBP-mediated oxidative C-S bond cleavage/annulation cascade is devised. This approach enables the controlled formation of carbonyl intermediates from benzyl thioethers to participate in annulation reactions with alkynes to offer privileged indenone skeletons.
