Abstract
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 7.alpha.-acylamino-2.alpha.-alkoxy-3-methyl-3-cephem-4-carboxylates first with either phenylsulfenyl chloride or a monosubstituted-phenylsulfenyl chloride where the substituent is either chloro, methoxy, methyl or acetoxy. The disulfide compounds produced in this invention are intermediates in the synthesis of the 7.beta.-acylamino-7.alpha.-alkoxy-3-methyl 1-oxa .beta.-lactam acids, a class of antibiotic compounds.
