ABSTRACT:
Silylating agents, such as 3-alkylsilyl-2-oxazolidinones, are useful for the preparation of penicillins and cephalosporins at low temperatures and in a short time. The process for preparing these compounds comprises reacting 2-oxazolidinone or 5-methyl-2-oxazolidinone with trimethylchlorosilane, dimethylchlorosilane or triethylchlorosilane, in the presence of an organic tertiary base acting as a hydrogen chloride removal agent.
