Procedure

6-amino-2,2-dimethylpenam-3-carboxylic acid (1.06 g.) was suspended in water (6 cc), and sodium tungstate dihydrate (10 mg.) was added thereto. To the stirred mixture was added, dropwise, 30% hydrogen peroxide (0.8 cc) while cooling in an ice bath over a period of 20 minutes, and the mixture was stirred for 1 hour at the same temperature. To this mixture was added, dropwise, cooled acetonitrile (90 cc), and the precipitate was collected by filtration and dried under reduced pressure to yield a pale yellowish powder (0.85 g.) of 6-amino-2,2-dimethylpenam-3-carboxylic acid-1-oxide.
