An efficient rhodium(III)-catalyzed coupling reaction of N-aryloxyacetamides with 6-diazo-2-cyclohexenones through a cascade redox-neutral C–H functionalization and aromatization has been developed. This novel and scalable transformation provides a straightforward way to construct unsymmetrical ortho-biphenols with broad substrate scope under mild and redox-neutral conditions. The synthetic utility of this approach is demonstrated in the late-stage functionalization of bioactive compounds and the synthesis of an optically active ortho-biphenol. (Figure presented.).

A novel silver(I)-catalyzed ring-contractive rearrangement of 5-substituted 6-diazo-2-cyclohexenones has been developed, providing a new and efficient access to 5-alkylidene-2-cyclopentenones. The AgOTf-catalyzed reaction proceeds through metal-carbenoid formation followed by endocyclic allyl [1,2] migration with excellent stereoselectivity and broad substrate scope.
Facile synthesis of 2-arylphenols via palladium-catalyzed cross-coupling of aryl iodides with 6-diazo-2-cyclohexenones

2-Arylphenols were conveniently synthesized from aryl iodides and 6-diazo-2-cyclohexenones, in moderate to excellent yields, via tandem Pd-catalyzed cross-coupling/aromatization. The preliminary results for the corresponding enantioselective version showe
