Thioalkylthio cephalosporin derivatives and intermediates.

摘要

Novel compounds of the formula I: QSR<2>SR<1>Het wherein Q is C1-C12 acyl or halogen; R<1> is a single bond or C1-C4 alkylene; and R<2> is a straight or branched C1-C4 alkylene; Het is 1,2,3-triazol-4-yl, or a derivative which is optionally protected at a nitrogen atom. The novel compounds are useful as intermediates for the production of thioalkylthio cephalosporin antibiotic compounds.
