ETT NYTT FOERFARANDE FOER FRAMSTAELLNING AV 6-AMINOPENICILLANSYRA-1,1-DIOXID

摘要

A novel process for the preparation of 6-aminopenicillanic acid-1,1-dioxide and its non-toxic, pharmaceutically acceptable salts by deacylation of a penicillin-1,1-dioxide or its salts of which the 3-carboxylic acid is protected by such an easily removable group that a "one-pot process" is possible.
