STUDIES ON 1-CARBADETHIACEPHEMS, PART III: SYNTHESIS OF 2,3-DIFUNCTIONALISED 1-CARBADETHIACEPHEM DERIVATIVES

A novel C(3) chlorination of p-nitrobenzyl 1-carbadethia-2-oxocephem 4-carboxylate 1 with sulphur dichloride is described.Reaction of the resulting 3-chloro-compound 8 with various thiols, and modifications at C(2) provided the title compounds.
