Process for producing cephalosporin analogs
摘要:
Optically active cephalosporin analogs are produced by an optically selective acylation reaction. The reaction is carried out in the presence of a microbial enzyme which catalyzes the selective optical acylation. The products thus obtained are useful as antibacterial agents.
