STRUCTURAL INVESTIGATION OF PARVIFOLINONE TRANSFORMATION PRODUCTS

Abstract

The structures of the transformation products of parvifolinone, trans-2,3-dihydro-3,6-dimethyl-7-acetoxy-2-carboxymethylenebenzopyran-4-one and 5-methyl-6-(2',4'-diacetoxy-5-methylphenyl)pyran-2-one, are proved by X-ray methods. The conformation of the dihydropyran-4-one moiety in the former is a distorted half-chair. The pyran-2-one ring in the latter is planar.
