The Rh‐catalysed hydroformylation of isopropylidenecyclohexane derivatives obtained by intramolecular diene cyclisations affords the corresponding aldehydes in good yields and in a completely chemo‐ and regioselective manner. Diastereoselectivities of ca. 90 % were achieved for all substrates when a bulky phosphite was used as the Rh ligand. Thestereochemical outcomes of the hydroformylation reactions were established by detailed NMR studies. The olfactory evaluation of the different aldehydes is also presented.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
