Novel odorant and/or flavoring substances are described. These are the compounds of the formula ##STR1## wherein: R.sup.1 represents methyl or ethyl, R.sup.2 represents hydrogen or methyl, the dotted line represents an optional carbon-carbon bond, n is 0 or 1, and, when n is O, R.sup.3 is hydrogen and R.sup.4 represents acetyl or propronyl, and, when n is 1, R.sup.3 represents methyl or ethyl and R.sup.4 represents hydrogen or methyl, with the exception of 1,4,4,7a-tetramethyl-3a,4,5,7a-tetrahydro-7(6H)-ind-1-enone. The compounds of formula I possess organoleptic properties which make them particularly suitable for use as odorant and/or flavoring substances.
