Pd-Catalyzed Desulfonative Cross-Coupling of Benzylic Sulfone Derivatives with 1,3-Oxazoles

Pd-Catalyzed Desulfonative Cross-Coupling of Benzylic Sulfone Derivatives with 1,3-Oxazoles

The Pd-catalyzed desulfonative cross-coupling reaction of benzylic sulfone derivatives with 1,3-oxazoles via a deprotonative pathway has been developed. Broad substrate scope for both sulfone and 1,3-oxazole partners is observed, affording a variety of 1,3-oxazole-containing triarylmethanes. Sulfone partners that are primary benzylic, secondary benzylic, and benzhydryl are all effective. Using this method, the straightforward synthesis of multiply arylated structures has been demonstrated.
