4-hydroxy-3-[(1S)-1,2,2-trimethylcyclopentyl]benzaldehyde [(−)-α-formylherbertenol 1], a herbertane-type sesquiterpene isolated from the leafy liverwortHerbertaadunca, from β-cyclogeraniol is described. The synthesis is based on the previously described preparation of an enantiopure 1,2,2-trimethylcyclopentane synthon from which the characteristic aromatic moiety of 1 is elaborated, using a Robinson annulation
