Abstract: The present invention relates to novel compounds of general formulae (la), (lb) and (Ic) and to the stereoisomers thereof. The compounds are useful as a fragrance or as flavor as they have a sandalwood like scent. The invention also relates to a method for imparting or modifying a scent or a flavor to a composition by including said compounds into such composition, to a fragrance containing composition and/or a fragrance material containing said compound and to a process for preparing these compounds. X is C(R4)-OH or C=O; R1 is selected from the group consisting of hydrogen, C1-C4-alkyl, C2-C4- alkenyl and C3-C4-cycloalkyl, R2 is selected from the group consisting of hydrogen, C1-C4-alkyl, C2-C4- alkenyl and C3-C4-cycloalkyl, R3 is C1-C4-alkyl, R3a is selected from the group consisting of hydrogen and C1-C4-alkyl, R3b is hydrogen or together with R3a is CH2; R4 is selected from the group consisting of hydrogen and C1-C4-alkyl.
