Microwave-Assisted Solid-Phase Synthesis of Cephalosporin Derivatives with Antibacterial Activity
摘要:
The reaction of heterocyclic acids with 7-amino-cephalosporanic acid adsorbed on basic alumina under microwave irradiation afforded the N-acylated cephalosporin analogues in satisfactory yield. All compounds were tested for their antibacterial activity; some of them showed significant antibacterial properties. Cefotaxime and cephalothin were used as reference drugs.

2-Substituted naptho[2,1-b]pyran-3-ones
have been synthesised by a novel one-pot method which involves
cyclocondensation of 2-hydroxy-1-naphthaldehyde with
5-methyl-1,3,4-thiadiazol-2-ylsulfanyl-,
1H-1,2,3,4-tetrazol-1-yl-, 1H-indol-3-yl-,
quinolin-8-yloxy- and 4-methylquinolin-2-yloxy-acetic acids in
the presence of DCCâDMSO using microwaves as well as
conventional heating.
