Abstract

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 7.alpha.-acylamino-2.alpha.-alkoxy-3-methyl-3-cephem-4-carboxylates first with an N-chloro halogenating agent, e.g., N-chlorosuccinimide, then with an aqueous suspension of mercury dichloride and cadmium carbonate. The disulfide compounds produced in this invention are intermediates in the synthesis of the biologically active 7.beta.-acylamino-7.alpha.-alkoxy-3-methyl 1-oxa .beta.-lactam antibiotic compounds.
