title: Ether-directed, stereoselective aza-Claisen rearrangements: synthesis of the piperidine alkaloid, alpha-conhydrine.
abstract: [reaction: see text] A new approach for the stereoselective synthesis of the piperidine alkaloid (+)-alpha-conhydrine and its pyrrolidine derivative has been developed using a palladium(II)-catalyzed, MOM-ether-directed aza-Claisen rearrangement and ring-closing metathesis to effect the key steps.
