L. Novak et al., REARRANGEMENT OF ALLYL ARYL ETHERS .1. REACTION OF HYDROQUINONE WITH CONJUGATED DIEN-OLS AND TRIEN-OL, Tetrahedron, 51(34), 1995, pp. 9367-9374
Thermal rearrangement of ethers 3 generated in situ from hydroquinone
1 and conjugated polyen-ols 2 afforded 2,3-dihydrobenzofuranols 5, 8 a
nd 10 with 1,3- and/or 3,5-shifts followed by acid-catalyzed intramole
cular cyclization.
