MARSUPSIN, A NEW BENZOFURANONE FROM PTEROCARPUS MARSUPIUM ROXB.

Chromatography of an ethyl acetate extract of defatted Pterocarpus Marsupium Roxb. (Leguminosae) heartwood over silica gel afforded marsupsin (1) which was characterized as a new 2-hydroxy-2-benzyl-3(2H)-benzofuranone by a consideration of physicochemical data and conversion to triacetylmarsupsin (3) and trimethylmarsupsin (tetramethylmaesopsin) (2).

Flavonoid synthesis based on photolysis of flavan-3-ols, 3-hydroxyflavanones, and 2-benzylbenzofuranones

Irradiation of flavan-3-ols, 3-hydroxyflavanones, and 2-benzylbenzofuranones in methanol leads mainly to photochemical opening of the heterocyclic ring, or to its complete photofragmentation, the products being trapped by reaction with the solvent. Fission of exocyclic C-O bonds also occurs, accompanied by intramolecular rearrangements. The course of these reactions is often dependent on the position and nature of substituents. The conversions provide novel routes to 1,3-diaryl-1-methoxypropan-2-ols, 1,3-diaryl-2,2-dimethoxypropan-1-ones, cis-3-methoxyflavanones, isoflavones, flavanones, and trans-chalcones, and hence to α-hydroxychalcones, cis- and trans-α-methoxychalcones, and 2-methoxy-2-(α-methoxybenzyl)benzofuranones.
