REGIOSELECTIVE PRENYLATION OF PHENOLS BY PALLADIUM CATALYST: SYNTHESES OF PRENYLPHENOLS AND CHROMANS

Tsukayama, Masao,Kikuchi, Makoto,Kawamura, Yasuhiko

, p. 1487 - 1490 (2007/10/02)

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).
