Regioselective Prenylation of Phenols by Palladium Catalyst: Syntheses of Prenylphenols and Chromans
摘要:
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).

The syntheses and full retinoid receptorcharacterization of a novel series of retinoicacidreceptor alpha (RAR alpha) antagonists, 1-5, are described. These compounds bind with high affinity to RAR alpha but were completely inactive in gene transactivation. They were also potent and effectiveantagonists of retinoicacid (RA) induced gene transcription at RAR alpha. Compounds 1-5 exhibited varying
