Electrochemically induced synthesis of β-lactams, by cyclization (via C3C4 bond formation) of haloamides XCHR 1 CONR 2 CHR 3 R 4 (X: Br, Cl), has been achieved in suitable solvent-supporting electrolyte solutions previously electrolyzed under galvanostatic control. The yields and the stereochemistry of the process are affected by the nature of substituents R 1 ...
A simple electrochemical synthesis of β-lactams has been developed using constant current electrolysis in a suitable solvent-supporting electrolyte solutions, with subsequent addition of bromoamides. The regio- and stereo-selectivity of the electrochemically-induced cyclization of bromoamides to β-lactams, via NC4 bond formation, has been evidenced. This synthesis avoids any addition of bases and...
