The Enzymatic Acylation Of These Nuclei With R-Methyl Mandelate Has Been Studied In Order To Evaluate Different Approaches For The Enzymatic Synthesis Of Cefonicid. The Best Results Have Been Obtained In The Acylation Of 7-Saca. Cefonicid (8) Was Recovered From The Reaction Mixture As The Disodium Salt In 65% Yield And About 95% Of Purity. Furthermore, Through Acylation Of 7-Aca, A "One-Pot"
