ABSTRACT:
By treating a primary or secondary alkenol having an olefinic bond in the sixth position relative to the carbon atom carrying the hydroxyl group and at least one methyl group in the fifth position relative to said carbon atom with a strong acid (e.g., 85 percent phosphoric acid), 2,2-dialkyltetrahydropyrans are produced via a cyclization reaction. The products have desirable fragrance characteristics.
