摘要
Trimethylsilyl or another easily hydrolyzed ester of 6-trimethylsilyloxycarbonylaminopenicillanic acid was prepared by bubbling dry carbon dioxide into ananhydrous solution of the corresponding 6-trimethylsilylaminopenicillanate and found to be a useful intermediate in the production of penicillins, e.g., amoxicillin and ampicillin, by its acylation in anhydrous media with the appropriate acid chloride or acid chloride hydrochloride.
