Claims16
A compound of the formula (I) ##STR12## wherein R.sup.1 is H, CH.sub.3, and CH.sub.2 CH.sub.3,
- R.sup.2 is CH.sub.3, and CH.sub.2 CH.sub.3, and
- R.sup.3 is CHO, and OCHO, provided that
- when R.sup.1 and R.sup.2 are both CH.sub.3, R.sup.3 is other than CHO.
A composition comprising a compound of the formula (II) ##STR13## and at least one compound selected from the group consisting of compounds of the formula (I) ##STR14## wherein R.sup.1 is H, CH.sub.3, and CH.sub.2 CH.sub.3,
- R.sup.2 is CH.sub.3, and CH.sub.2 CH.sub.3, and
- R.sup.3 is CHO, and OCHO, provided that
- when R.sup.1 and R.sup.2 are both CH.sub.3, R.sup.3 is other than CHO.

- R.sup.2 is CH.sub.3, and CH.sub.2 CH.sub.3, and
- R.sup.3 is CHO, and OCHO, provided that
- when R.sup.1 and R.sup.2 are both CH.sub.3, R.sup.3 is other than CHO, in combination with at least one of a carrier and additional perfumery material.
A fragrance composition comprising a compound of the formula (II) ##STR16## in combination with at least one of a carrier and additional perfumary material.
A fragrance composition comprising a composition which comprises a compound of the formula (II) ##STR17## and at least one compound selected from the group consisting of compounds of the formula (I) ##STR18## wherein R.sup.1 is H, CH.sub.3, and CH.sub.2 CH.sub.3,
- R.sup.2 is CH.sub.3, and CH.sub.2 CH.sub.3, and
- R.sup.3 is CHO, and OCHO, provided that
- when R.sup.1 and R.sup.2 are both CH.sub.3, R.sup.3 is other than CHO, in combination with at least one of a carrier and additional perfumary material.
