Abstract
7-Substd. amino de-acetoxy cephalosporane acids and esters of formula (I) (in which R1 is H or C, R2 is a 1-10C acid gp. which can include O, S or N, and R3 is H, a heterocyclic base cation, or other gp.), are made by reacting a cpd. of formula (II) with a silylating agent consisting of N-trimethylsilyl 2-oxazolidinone or N,N'-bis trimethylsilyl sulphamide. Reaction is in inert solvent at 100-120 deg.C in presence of an acid salt.
