Abstract
6-Aminoacylamidopenicillanic acid or 7-amino-acylamidocephalosporanic acids are produced in high yields by acylating 6-aminopenicillanic acid or 7-aminocephalosporanic acid with an amino acid, or a functional equivalent thereof, having its amino group protected with N,N-disubstituted .beta.-keto acid amide, and then removing the protecting group from the resulting protected 6-aminoacylamidopenicillanic acid or protected 7-aminoacylamidocephalosporanic acid by hydrolysis.
