An efficient DBU-catalyzed conjugate addition of 5H-oxazol-4-ones to o-hydroxyphenyl-substituted p-quinone methides has been developed, affording the valuable diarylmethanes in high yields with excellent diastereoselectivity. This strategy demonstrates a robust access to a wide range of diarylmethane derivatives possessing biologically significant o-hydroxyphenol and p-hydroxyphenol moieties under mild reaction conditions.

5H-Alkyl-2-phenyl-oxazol-4-ones, a little-known heterocyclic ring system, are readily available via a microwave-assisted, sodium fluoride catalyst cyclization of mono-α-haloimides, which in turn are accessed by N-acylation of benzamides with α-bromo acid
