Process for preparation of 3-hydroxymethylcephems |
| abstract |
3-Hydroxymethyl-2-cephems are provided by (1) reacting a 2-halomethylcephem compound with a γ-hydroxycarboxylic acid salt or a δ-hydroxycarboxylic acid salt and (2) reacting the novel γ or δ-hydroxy esters thereby obtained with a protic acid. The 3-hydroxymethylcephems provided by the process of this invention are useful intermediates for the preparation of known cephalosporin antibiotics. |
