Copper-Catalyzed Oxidative Benzylic C(sp3)?H Cyclization for the Synthesis of β-Lactams

β-Lactams are important structural motifs because of their ubiquity in natural products and pharmaceuticals. We report herein a Cu-catalyzed intramolecular oxidative C(sp3)?H amidation for the synthesis of β-lactams using tBuOOtBu. This method

Halogen-metal exchange reactions of bromoaryl-substituted β-lactams

β-Lactams are quite susceptible to ring opening when exposed to nucleophilic reagents. The robustness of a variety of bromo- and iodoarenes containing electrophilic functional groups toward alkyllithium reagents during the halogen-lithium exchange process

One-pot synthesis of β-lactams from aldimines and ketene silyl acetals by tandem lewis base-catalyzed Mannich-type addition and cyclization

An efficient method for one-pot synthesis of β-lactams from aldimines and ketene silyl acetals by tandem Lewis base-catalyzed Mannich-type addition and cyclization, namely reaction of benzylideneanilines and trimethylsilyl enolates derived from esters or thioesters was established by using a Lewis base catalyst such as lithium acetate, N-lithio-2-pyrrolidone, potassium salt of phthalimide or lithium methoxide in DMF at room temperature to afford the corresponding β-lactams in good to high yields with moderate trans-selectivities.

Stereoselective synthesis of trans β-lactams through iridium-catalyzed reductive coupling of imines and acrylates

(Matrix presented) Iridium-catalyzed reductive coupling of acrylates and imines provides trans β-lactams with high diastereoselection. The optimal catalyst allows for the synthesis of trans β-lactams bearing aromatic, alkenyl, and alkynyl side chains. Thi

The Hydrolysis of Azetidinyl Amidinium Salts. Part 2. Substituent Effects, Buffer Catalysis, and the Reaction Mechanism

The hydrolysis of azetidin-2-ylideneammonium salts gives a mixture of β-lactams, by exocyclic C-N bond fission, and β-amino amides, by endocyclic C-N bond breakage and opening of the four-membered ring.The reaction is general-base catalysed and more β-lactam is formed using a less basic buffer.The mechanism of the buffer-catalysed reaction is the general-acid-catalysed breakdown of a reversibly formed neutral tetrahedral intermediate.The Broensted α-values vary with substituents in the amidinium salt so that they decrease with increasing electron withdrawal in the nitrogen amine which is expelled.Electron-withdrawing substituents attached to either nitrogen of the amidinium salt favour expulsion of that leaving-group amine.The Broensted β1g for endocyclic C-N-bond fission and β-amino amide formation is -0.52 whereas that for exocyclic C-N bond fission and β-lactam formation is -0.83.Substituent effects on the nitrogen amine which is not expelled but forms the product amide or β-lactam generate βp values of -0.71 and -0.07, respectively.Changes in structure-reactivity relationships with substituents are examined by an analysis of the reaction mechanism.
