ChemInform Abstract: Pigments of Fungi. Part 15. An Efficient, Unambiguous Route to Unsymmetrically Substituted Dibenzyl Acyloins and Their Use in the Synthesis of Fungus Pigments of the Pulvinone and Grevillin Types.

Abstract

AbstractDibenzyl acyloins such as (III) including those bearing unsymmetrically disposed aryl residues are assembled in high yield by reaction between the silyl ethers (I) of arylacetaldehyde cyanohydrins and the Grignard reagents (II).
