Chiral α‐amino ketones are excellent nucleophiles for stereoselective palladium‐catalyzed allylic alkylations. Both chiral as well as achiral allylic substrates can be applied, while the stereochemical outcome of the reaction is controlled by the chiral ketone enolate. The substituted amino ketones formed can be reduced stereoselectively, and up to five consecutive stereogenic centers can be obtained

The recently reported natural product Sch 382583 (1), an inhibitor of peptide deformylase, has been synthesized in 16 steps from commercially available starting materials. The three chiral centers were set by a combination of chiral auxiliary and chiral pool approaches. The succinate 5 and piperazic acid 9 moieties were obtained by Evans oxazolidinone imide enolate alkylation and hydrazination/cyclization
