worin R 1 = R 4 = CH 3 und R 2 = R 3 = H noder nR 1 = R 2 = R 3 = H und R 4 = CH 3 , noder nR 1 + R 2 = -CH 2 CH 2 - und nR 3 = H und R 4 = CH 3 , noder nR 1 = R 4 = CH 3 und R 2 + R 3 = -CH 2 - noder nR 1 = CH 3 und R 2 = R 3 = H und nR 4 = CH 2 CH 3 noder nR 1 = R 2 = R 4 = CH 3 und nR 3 = H sind, und nR 5 = H (bevorzugt) oder CH 3 ist. The invention relates to new fragrances. These are the compounds of the formula wherein R 1 = R 4 = CH 3 and R 2 = R 3 = H or R 1 = R 2 = R 3 = H and R 4 = CH 3 , or R 1 + R 2 = -CH 2 CH 2 - and R 3 = H and R 4 = CH 3 , or R 1 = R 4 = CH 3 and R 2 + R 3 = -CH 2 - or R 1 = CH 3 and R 2 = R 3 = H and R 4 = CH 2 CH 3 or R 1 = R 2 = R 4 = CH 3 and R 3 = H, and R 5 = H (preferred) or CH 3 . |
