✦ Synopsis


Abstract

Benzhydrylic esters of 3‐unsubstituted cephem‐4‐carboxylic acids of types 9 and 10 (Scheme 2) are prepared by decarbonylation of esters of 3‐formylcephem compounds of type 2 with tris‐triphenylphosphine‐rhodium chloride. The preparation of the starting materials 2 and 5, as well as of the nucleus 13 is described.
