Chemical Studies of the Proteaceae. Vii. An Examination of the Woods of 17 Species for Resorcinol Derivatives

Abstract

No phenols could be isolated from the woods of nine Proteaceae species, but eight others yielded mixtures of 5-n-alk(en)ylresorcinols. Two of these also contained substances of the striatol type. Cardwellia sublimis gave a high yield of (-)-bornesitol.Syntheses of 5-heptadecylresorcinol, bilobol and some degradation products of 5-n-alkenylresorcinols are described.
