Abstract

A procedure for the preparation of odorant compounds of the formula **(See formula)** wherein R1 and R2 signify hydrogen or methyl, but at least one of the symbols R1 or R2 signifies hydrogen; X represents one of the radicals (see formula); R3 is isopropyl, isopropenyl or isopropylidene, and the symbol (see graph) represents a single C-C or double C = C bond characterized by reacting a compound of the formula **(See formula)** optionally after previous conversion to an enamine, with a compound of the formula **(See formula)** and, optionally, hydrogenate the reaction product of the formula **(See formula)** to obtain a compound of the formula **(See formula)** this compound is optionally reduced to a compound of the formula **(See formula)** or, optionally, reducing the reaction product of formula Ia, to a compound of the formula **(See formula)** and, optionally, to hydrogenate this compound (R1, R2 and R3, in formulas Ia-Id, II and III have the meaning assigned to them for formula I).
