Abstract
The invention comprises 4-ethylidene-chromans substituted in the b -position of the ethylidene group by a 11-alkyl-21,51 -dioxocyclopent-11-yl- or 11-alkyl-21,51 dioxo-cyclohex-1-yl group, and their preparation by condensation of a 4-vinyl-chroman-4-ol with a 2-alkyl-cyclopentane or cyclohexane-1,3 dione.
