Process for preparation of 3-halomethylcephems |
| abstract |
3-Halomethyl-3-cephems are provided by reacting a 3-methylenecepham with an alkali metal salt of a lower alcohol or a bicyclic amidine base in the presence of a positive halogenating agent at a temperature ranging from -80° to about 20° C. The 3-halomethylcephems provided by this invention are useful intermediates for the preparation of known cephalosporin antibiotics. |
