Euparin (4a) and related benzofurans (4b-e, g) were synthesized by conversion of the corresponding o-(3-hydroxy-3-methylbutynyl)phenyl tosylates (2) in the presence of base into the 2-(1-hydroxy-1-methylethyl)benzofurans (3), followed by dehydration in hi

The palladium-catalyzed coupling reaction of iodophenols (1) with 2-methyl-3-butyn-2-ol gave alkynylphenols (2).Catalytic hydrogenation of 2 over Raney nickel and the subsequent dehydration of the resultant alkylphenols (3) gave regioselectively the desired prenylphenols (4).Dehydration of alkylphenols (3f-h) gave chromans (7).
