<p>Novel odorants or odorant compositions which are characterized by a content of one or more compounds selected from the group consisting of tetrahydrofurans of structures (I) or tetrahydropyrans of structure (I'), wherein R can be an aliphatic chain, namely a chain of at least four carbon atoms substituted with at least three methyl groups in the chain, a monocarbocyclic residue, where monocarbocyclic refers to one ring of 5-8 carbon atoms, and with at least two methyl groups, e.g. on the ring, or the residue of a bicyclic ring system, where bicyclic refers to two carbon rings, having between 5-8 carbon atoms, fused together, the bicyclic system substituted with at least two methyl groups, or R + R3 can also form a spirocyclic moiety in case of the tetrahydrofurans, and wherein R1 = H or CH¿3?, or a higher alkyl group, R?2¿ = H, CH¿3?, or a higher alkyl group, R?3¿ = H, or CH¿3?, R?4 and R5¿ = H, CH¿3?, or a higher alkyl group, and wherein R?1 = R2¿ ¸ H.</p> |
