  • Patent number: 6670477
    Abstract: A process for making enantiomerically enriched 4-piperidinylglycine having the formula (I), said process comprising (a) combining N-protected glycine ester with 4-piperidone to form didehydroamino acid ester; (b) reducing the didehydroamino acid ester with hydrogen gas in the presence of a rhodium catalyst selected from the group consisting of (R,R)-BPE-Rh; (S,S)-BPE-Rh; (R,R)-DuPHOS-Rh; (S,S)-DuPHOS-Rh; and combinations thereof; whereby a protected compound is formed; and (c) removing the protecting groups from the protected compound, whereby the 4-piperidinylglyeine having the formula (I) is formed, wherein X− is an anion wherein X is independently a halogen; and “*” designates an asymmetric carbon having (R)- or (S)-configuration. The process of the invention yields an enantiomerically enriched (R)-4-piperidineglycine or (S)-4-piperidineglycine.

  • Patent number: 6596260
    Abstract: The invention relates to an aerosol container for pharmaceutically active aerosols that are to be administered in predetermined amounts and that are supplied in the container in the form of a suspension, the suspension also comprising, in addition to a pharmaceutically active substance, at least a propellant gas. The aerosol container has a metering valve that comprises a metering chamber and a valve stem. In a first position of the valve stem, the metering chamber is in communication with the interior of the container and has been filled with a predetermined amount of the aerosol. In a second position of the valve stem, the amount of aerosol disposed in the metering chamber is released. The propellant gas is an alternative propellant gas that is free of fluorochlorohydrocarbons, preferably a propellant gas that comprises only fluorohydrocarbons, and the inner wall of the container is coated with a plastics coating.
