the conversion of 6‐acyl cyclohexenones into 2,6‐disubstituted 2,3,4,5‐tetrahydropyridines and, after diastereoselective reduction, 2,6‐syn‐disubstituted piperidines has been developed. The scope of this process is outlined by the synthesis of cis‐2‐methoxycarbonylmethyl‐6‐pentylpiperidine and the first total synthesis of the Elaeocarpus‐derived alkaloid (−)‐grandisine G (see scheme).
