The degradation of manool (I) to the known intramolecular ketal III and its new stereoisomer IV is described. Structure and configuration of both stereoisomers are discussed on the basis of further chemical transformations and of the results of NMR.‐spectroscopy. Both ketals possess a powerful odour of a novel amber type.
