CHEMISTRY OF HOP CONSTITUENTS: VIII.* OXIDATION OF HUMULONE AND COHUMULONE

Abstract

The preparation of humulinone by the oxidation of humulone affords in our hands a single substance, whilst the similar oxidation of cohumulone leads to a single cohumulinone. The physical and chemical properties of humulinone and cohumulinone suggest that they may be identical with the compounds of m.p. 70–71° C. and m.p. 104–105° C., respectively, described by Verzele & Govaert.
