The invention concerns novel odorants, namely derivatives of dihydrocampholenic aldehyde having the formula ##STR1## wherein R is ##STR2## one of the dotted lines in each of (a) and (b) represents an additional bond, and, R.sup.1, R.sup.2 and R.sup.3 are selected from the group consisting of hydrogen and alkyl groups of from one to four carbon atoms, with the proviso that R.sup.3 is present only when the additional bond is between the carbon atoms designated as .beta. and .gamma.. The invention also concerns odorant compositions containing the dihydrocampholenic aldehyde derivatives and methods for making same.
