    摘要: Penicillin sulfoxide esters having the sulfoxide group in the .alpha.-configuration are reacted with an N-chloro halogenating agent at a temperature between about 70.degree. C. and about 120.degree. C. in the presence of an alkylene oxide and preferably also calcium oxide to produce 2-chlorosulfinyl-azetidin-4-one intermediates. The chlorosulfinyl intermediates are then treated with a Friedel-Crafts catalyst, for example, stannic chloride to provide a 3-exomethylenecepham .beta.-sulfoxide. The latter compounds are useful in the preparation of 3-alkoxy and 3-halo substituted cephalosporin antibiotic compounds.

    摘要: Cephalexin was produced by hydrolysis of its methoxymethyl ester which in turn was produced by reaction of 2-phenylglycine chloride hydrochloride with an imino ether of methoxymethyl 7phenoxyacetamido-3-methyl-ceph-3-em-4-carboxylate which had been prepared by reaction of an alcohol with the corresponding iminochloride made by treatment with PCl5 of methoxy-methyl 7phenoxyacetamido-3-methylceph-3-em-4-carboxylate. The last was made by thermal rearrangement of the methoxymethyl ester of phenoxymethylpenicillin sulfoxide.
