Abstract
Aldehydes are produced by cleaving 2,2-dialkyltetrahydropyrans bearing two hydrogen atoms in the sixth position with a strong acid. The 2,2-dialkyltetrahydropyran can be formed in situ by contacting the strong acid with a primary 6-alken-1-ol having at least one methyl group in the fifth position so that cyclization occurs.
