The synthesis of 6-aminopenicillanic acid (1) was followed very quickly by the appearance of several semi-synthetic penicillin homologues. The first of the semi-synthetic penicillins to become widely available after undergoing clinical trials was alpha-phenoxyethyl penicillin (Broxil) (2). The accumulated results of these studies demonstrated that phenoxyethyl penicillin possessed few advantages over alpha-phenoxymethyl penicillin (penicillin V). Its prime importance lay not so much in its antibacterial activities as in the demonstration that clinically active penicillins could now essentially be made to order. A pressing need existed for an agent with the major advantages of penicillin-G—a lack of toxicity, bactericidal efficiency, economy,
