This invention discloses and claims methods for inhibiting bacterial β-lactamases and treating bacterial infections by inhibiting bacterial β-lactamases in man or an animal comprising administering a therapeutically effective amount to said man or said animal of a compound, or pharmaceutically acceptable salt thereof, of formula (I) either alone or in combination with a β-lactamine antibiotic wherein said combination can be administered separately, together or spaced out over time. Pharmaceutical compositions comprising a compound of formula (I), or a combination of a compound of formula (I) and a therapeutically effective amount of a β-lactamine antibiotic, and a pharmaceutically acceptable carrier are also disclosed and claimed.

The present invention relates to a method for producing an optically active 3-aminopiperidine or salt thereof. In the method, a racemic nipecotamide is stereoselectively hydrolyzed to obtain an optically active nipecotamide and an optically active nipecotic acid in the presence of an enzyme source derived from an organism, and then the optically active nipecotamide is derived into an optically active aminopiperidine or salt thereof by aroylation, Hofmann rearrangement, deprotection of the amino group and further deprotection; or the optically active nipecotamide is derived into an optically active aminopiperidine or salt thereof by selective protection with BOC, Hofmann rearrangement and further deprotection. It is possible by the present invention to produce an optically active 3-aminopiperidine or salt thereof useful as a pharmaceutical intermediate from an inexpensive and easily available starting material by easy method applicable to industrial manufacturing.
