Compounds represented by the structural formulae <IMAGE> (I) <IMAGE>(II) or <IMAGE>(III) wherein n is an integer 0 or 1; A, B and C each independently represent hydrogen or alkyl having from 1 to 3 carbon atoms, provided that when n is 0 at least one of A, B or C cannot be hydrogen; D and E each independently represent hydrogen, alkyl having from 1 to 6 carbon atoms, provided that the sum of the carbon atoms in D and E does not exceed 6, alkoxy having from 1 to 5 carbon atoms or <IMAGE> wherein R represents alkyl having from 1 to 6 carbon atoms or aryl, provided that if either D or E is alkoxy or <IMAGE> then the other substitutent D or E must be hydrogen; m is an integer 1 through 8; F and G represent hydrogen or alkyl having from 1 to 3 carbon atoms; X represents <IMAGE> WHEREIN P IS AN INTEGER 0 THROUGH 2 AND I and J each independently represent hydrogen or methyl, provided that if p is 0 then m must be greater than 2; provided that the sum of the carbon and oxygen atoms in the compound is no greater than 23, are useful as fragrances or as components in fragrance compositions. These compounds have very pleasant, strong and long-lasting aromas. Novel compounds are also disclosed. |
