Abstract
6-.beta.-Substituted penicillanic acids and derivatives thereof as useful enhancers of the effectiveness of several .beta.-lactam antibiotics against many .beta.-lactamase producing bacteria, and 6-.beta.-substituted penicillanic acid derivatives wherein the carboxy group is protected by a conventional penicillin carboxy protecting group as useful intermediates leading to said synergistic agents. A process for converting 6,6-disubstituted penicillanic acid derivatives to the corresponding 6-.beta.-substituted penicillanic acid congeners.
