In conclusion, we have developed a novel and facile
rhodium(III)-catalyzed the carbonyl in sulfoxonium ylides
assisted ortho- C−H functionalization of sulfoxonium ylides
followed by intramolecular annulation with hydroquinones.
This protocol leads to the efficient formation of 2-hydroxy-6H-
benzo[c]chromen-6-one derivatives, proceeding with the
cleavage of C(O)−C bond in sulfoxonium ylides where the
carbonyl in sulfoxonium ylides served as chelation group and
sulfoxonium ylides served as the aroyl source. This protocol
featured with high chemo-selectivity and functional group
tolerance.
