Ether-Directed, Stereoselective Aza-Claisen Rearrangements: Synthesis of the Piperidine Alkaloid, α-Conhydrine
摘要:
[GRAPHICS]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.
