In particular, the authors made judicious use of known chemistry in the initial reaction of C6-O-TMS acetal with an aryl aldehyde followed by the TMSOTf-catalyzed cyclization with O4 to a ...

Less often, an alkyl or aryl halide is treated with a carboxylate salt. But these methods don’t work in the case of vinyl acetate and other vinyl esters because vinyl alcohols aren’t stable—they ...
