Interaction of 2,5-dialkylphenols (2,5-dimethylphenol and 2-isopropyl-5-methylphenol) with isobutyric aldehyde and nitriles catalyzed by concentrated sulfuric acid leads to the formation of 1-R-9-alkyl-3,3,6-trimethyl-2-azaspiro[4.5]deca-6,9-dien-8-ones and 1-R-9-alkyl-3,3,6-trimethyl-2-azaspiro[4.5]deca-1,6,9-trien-8-ones.
