A simple route to the highly substituted enantiomerically pure 1,3‐alkadienes 3 is provided by the rearrangement of the adduct prepared from the allene 1 (CbC(O)NiPr 2 , R′ =; (C 6 H 5 CH 2 )) and the ketene N,O‐acetal 2 (RCH 3 ). The transition state for the rearrangement could be determined from knowledge of the absolute configurations of the educt 1 and the product 3.
