Paragraph 0032-0035, (2018/02/04)
The invention relates to a zabofloxacin intermediate and a synthetic method thereof. The synthetic method comprises the following steps: by adopting glycinate hydrochloride as a starting raw material, carrying out addition with ethyl acrylate, then cyclizing under an alkaline condition, and then carrying out methylolation reaction with formaldehyde under the alkaline condition; then reacting with methoxyamine hydrochloride into imine; and finally reacting with paratoluensulfonyl chloride into ester to obtain a target compound. The process disclosed by the invention has the advantages of easiness for raw material obtaining, low price, moderate yield and easiness for operation.

scheme or table, p. 780 - 786 (2009/04/07)
The synthesis of a new series of 1β-methylcarbapenems having pyrrolidine and piperidine moieties is described. Their in-vitro antibacterial activities against both Gram-positive and Gram-negative bacteria were tested and the effect of substituents on the pyrrolidine ring was investigated. A particular compound III b having an oxime-pyrrolidine moiety showed the most potent antibacterial activity.
