Synthesis of Vismiaphenone-B: A Naturally Occurring Prenylated Benzophenone

Vismiaphenone-B, 5-C-prenyl-2,6-dihydroxy-6'',6''-dimethylchromenobenzophenone (II), has been synthesised starting from 2,4,6-trihydroxybenzophenone (V).V on prenylation with prenyl bromide in the presence of methanolic sodium methoxide yields three products, viz. 3,5-di-C-prenyl-2,4,6-trihydroxybenzophenone (VI), 2,6-dihydroxy-4-O-prenylbenzophenone (VII) and a brown oil, which could not be characterised.VI on cyclodehydrogenation with DDQ affords II, identical in all respects (UV, IR and PMR) with a natural sample.

Synthesis of Naturally Occurring Prenylated Benzophenones. Vismiaphenone A, Vismiaphenone B, and Isovismiaphenone B

2,4,6-Trihydroxybenzophenone on prenylation with 2-methyl-3-buten-2-ol in the presence of (C2H5)2O*BF3 yielded 2,4,6-trihydroxy-3,5-diprenylbenzophenone (3), 2,6-dihydroxy-4-prenyloxybenzophenone, 2,6-dihydroxy-3-prenyl-4-prenyloxybenzophenone, a benzodip
