Methyl substituted pinyl oxopentenes, organoleptic uses thereof and

Abstract

Described are methyl substituted pinyl oxopentenes and mixtures of same and uses thereof in augmenting or enhancing the aroma or taste of consumable materials including foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, perfume compositions, perfumed articles (including perfumed polymers, solid or liquid cationic, anionic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, optical brightener compositions, and cosmetic powders), colognes, smoking tobacco compositions and smoking tobacco articles including cigars, cigarettes and integrated and separate filters therefor. Also described are processes for preparing such compounds including the steps of reacting alpha and/or beta pinene with carbon monoxide and hydrogen via an oxo reaction in the presence of a catalyst to produce a mixture of aldehydes and then reacting the resulting mixture of aldehydes with methyl ethyl ketone in the presence of a basic catalyst to produce the compounds of our invention.
