The heartwood of Berchemia zeyheri yielded 4,6-dihydroxy-3-(4- hydroxybenzyl)-3-methylbenzo[b]-furan-2(3H)-one and the 5- and 7-[2-(4- couznaroyl)]maesopsins, benzofuranoid-type flavonoids with molecular backbones reminiscent of products of benzylic acid rearrangement.
A Novel Photochemical Structural Inversion: The First Methoxy-Hydroxymethyl Isomerization

Photolysis of 4-methoxybenzofuran-3(2H)-ones provides the first example of structural inversion of an arylmethoxy-group to the corresponding hydroxymethyl function.Suitable structural parameters permit subsequent rearrangement of the heterocyclic ring to 5-hydroxyisochroman-4-ones.By contrast photolysis of the isomeric 4-methoxybenzofuran-2(3H)-one leads directly to the deoxybenzoin analogue.
