Diversity-oriented preparation of enantiopure spirocyclic 2-azetidinones from α-oxo-β-lactams through barbier-type reactions followed by metal-catalyzed cyclizations

Novel, simple, and convenient strategies to diversely functionalized spirocyclic β-lactams have been developed by using different metal-mediated carbonyl addition/cyclization reaction sequences. Spirocyclization precursors, 2-azetidinone-tethered homoally

N1-C4 β-lactam bond cleavage in the 2-(trimethylsilyl)thiazole addition to β-lactam aldehydes: Asymmetric synthesis of spiranic and tertiary α-alkoxy-γ-keto acid derivatives

Starting substrates, enantiopure spiranic or 3-substituted 3-alkoxy-4-oxoazetidine-2-carbaldehydes, were prepared from (R)-2,3-O- isopropylideneglyceraldehyde derived azetidine-2,3-diones by sequential Barbier-type addition reactions followed by hydroxy f

Metal-assisted synthesis of enantiopure spirocyclic β-lactams from azetidine-2,3-diones

A novel approach to enantiopure spirocyclic β-lactams has been developed by using different intramolecular metal-catalyzed cyclization reactions in monocyclic unsaturated alcohols. A novel approach to enantiopure spirocyclic β-lactams has been developed b
