| titleOfInvention | PROCEDURE FOR PREPARING NEW DERIVATIVES OF CEPHALUS- PORINA |
| abstract | Procedure for preparing new cephalosporin derivatives. When the acid is used, the protection of the amino group is carried out by any method known per se for blocking an amine function without otherwise touching the molecule. It is necessary to use an easily removable group such as tert-butoxycarbonyl or trichloro-2,2,2-ethoxycarbonyl group. It is particularly advantageous to use the tert-butoxycarbonyl group, which can be introduced by di-tert-butyl bicarbonate, tert-butyl azidoformate, tert-butyl chloroformate or mixed tert-butyl p-nitrophenyl carbonate. |
