Synthesis and structure-activity relationship of C-3 benzoyloxymethyl cephalosporins exhibiting anti-MRSA activities
摘要:
A series of cephalosporins bearing C-3 benzoyloxymethyl groups were prepared and evaluated for their anti-MRSA activity and plasma stability. They exhibit excellent in vitro activity (MIC = 0.06 similar to 2 mu g/mL) against MRSA and excellent stability in human plasma. (C) 1997 Elsevier Science Ltd.

10-phenanthroline, PdI2, and Tol-BINAP, for the first time allows the decarboxylative coupling of carboxylic acids with aryl triflates. In contrast to previous decarboxylative couplings that remained limited to certain activated carboxylates, e.g., ortho-substituted benzoates, this halide-free protocol is generally applicable to aromatic carboxylic acid salts regardless of their substitution pattern.
