Dihydrobenzofurans via dienone-phenol rearrangement of spirooxetanes from photoaddition of quinones with electron donor olefins

Article abstract of DOI:10.3987/com-95-7336

Photoaddition of electron donor olefins such as vinyl ethers and stilbene to variously methyl- and halogeno-substituted 1,4-benzoquinones resulted in the formation of dihydrobenzofurans via a dienone-phenol rearrangement of the primary product spirooxetanes.
