## Abstract

This study explores the selective oxidative scission
of bicyclo[2.2.2]octenones
derived from masked o-benzoquinones (MOBs). By employing
the fragmentation of ketoximes and Schmidt-type reactions, we achieved
the cleavage of α-dimethoxy carbonyl groups to yield highly
functionalized cyclohexene frameworks, showcasing the expanding synthetic
utility of bicyclo[2.2.2]octenones in complex organic synthesis. The
methodologies developed are anticipated to contribute to advancements
in organic and pharmaceutical chemistry.
