An efficient method for the reduction of cephalosporin sulfoxides

An efficient and convenient method for the reduction of cephalosporin sulfoxides to their corresponding sulfides by Lawesson reagent is reported.

Azetidinone alcohol disulfides and process for cyclization

Azetidinone alcohol disulfides are synthesized by reduction of the corresponding aldehydes. The azetidinone alcohol disulfides are the substrates for a process which cyclizes these compounds to 1-oxa β-lactam compounds, employing a cyclizing reagent chose

Unsymmetrical azetidinone aldehyde disulfides and process

Aryl 4R[1-(2-N-3-methyl-4-al-Z-but-2-ene-oate)-2-oxo-3S-acylamino azetidinone]disulfides are prepared by reacting the corresponding 7α-acylamino-2α-alkoxy-3-methyl-3-cephem-4-carboxylates first with either phenylsulfenyl chloride or a monosubstituted-phen

Symmetrical azetidinone aldehyde disulfides and process

4R,4'R bis[1-(2-N-3-methyl-4-al-Z-but-2-ene-oate)-2-oxo-3S-acylamino azetidine]disulfide compounds are prepared by reacting the corresponding 7α-acylamino-2α-alkoxy-3-methyl-3-cephem-4-carboxylates first with an N-chloro halogenating agent, e.g., N-chloro
