Cephalosporins are important antibiotics. We synthesized new cephalosporin analogs containing novel side chains of methyl, propyl, benzyl, and phenoxy groups. Four synthetic methods with N-alkylation and N-acylation at position C-7 and esterification at position C-4 of 7-aminodesacetoxycephalosporanic acid are reported here.
