, (2008/06/13)
A process for the preparation of chloromethyl esters of penicillanic acids, using iodochloromethane or bromochloromethane and a tetraalkylammonium salt of the penicillanic acid, and their use in processes for the synthesis of penicillanic acid esters, using a halomethyl ester and the tetraalkylammonium salt of the penicillanic acid, which readily hydrolyze in vivo to antibacterial penicillins and the beta-lactamase inhibitor penicillanic acid sulfone.
Bis-esters of methanediol with acetonides of ampicillin or amoxicillin and penicillanic acid 1,1-dioxide

Bis-esters of methanediol wherein one hydroxy group of the methanediol is esterified with the carboxy group of hetacillin (or of the p-hydroxy analog of hetacillin) and the other hydroxy group of the methanediol is esterified with penicillanic acid 1,1-dioxide. These orally effective compounds have a particularly broad spectrum of antibacterial activity in mammals, and have an unusually long serum half-life.
