Pigments of Fungi. XV An Efficient, Unambiguous Route to Unsymmetrically Substituted Dibenzyl Acyloins and their Use in the Synthesis of Fungus Pigments of the Pulvinone and Grevillin Types

Dibenzyl acyloins including those bearing unsymetrically disposed aryl residues are assembled in high yield by reaction between the O-trimethylsilyl ethers of arylacetaldehyde cyanohydrins and benzyl Grignard reagents.These acyloins are deprotonated with

SYNTHESIS OF FUNGUS PIGMENTS OF THE GREVILLIN AND PULVINONE TYPES FROM BENZYLACYLOINS.

Grevillin-B (2) and 3',4',4'-trihydroxypulvinone (3), principal colouring matters of the myorrhizal toadstool Suillus grevillei, are synthesised in good yield from a common precursor in the form of benzylacyloin 6.
