Abstract:
The present invention relates to a method for the regioselective hydroformylation of polyunsaturated acyclic hydrocarbons, which are 1, 3 butadienes, which, in the 2 position, bear a saturated or monounsaturated or polyunsaturated acyclic hydrocarbon radical. The present invention also relates to the production of secondary products of these hydroformylation products, especially of ambrox.

Claim (Index 31):
A process for the preparation of (\u2212)-ambrox (V) in which a1) (6E)-7,11-dimethyl-3-methylidenedodeca-1,6,10-triene (II.1) is subjected to a reaction with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst which comprises a rhodium complex with at least one phosphorus chelate compound as ligand, wherein a reaction mixture is obtained which comprises at least 50.1% by weight, based on the total weight of the reaction mixture, of (7E)-8,12-dimethyl-4-methylenetrideca-7,11-dienal (I.1) b1) the reaction mixture obtained in step a) or a fraction thereof enriched in at least one compound of the general formula (I.1) is subjected to a hydrogenation, wherein a reaction mixture is obtained which comprises the compound (III.1) c1) the compound (III.1) is subjected to an at least partial isomerization, giving (3E,7E)-homofarnesol (IV.1) d1) the (3E,7E)-homofarnesol (IV.1) is subjected to a cyclization to give (\u2212)-ambrox (V).
