  • Enantioselective synthesis of 3-aminopyrrolidines
    Patent number: 6211395
    Abstract: The invention relates to a process of preparing a chiral compound of the formula: wherein R1 is selected from the group consisting of hydrogen and lower alkyl, and R2 and R2′ are the same, and R2 and R2′ are selected from a group consisting of hydrogen and primary alkyl, or R2 and R2′ taken together form a C3 to C6 cycloalkyl, comprising the steps of chirally reducing a &bgr;-keto ester to afford a &bgr;-hydroxy ester, activating the &bgr;-hydroxy ester by treatment with a sulfonic acid or a derivative thereof to provide an activated compound having sulfonate leaving group, displacing the sulfonate leaving group with an azido moiety, or treating the activated compound with an alkylamine, deprotecting and cyclizing to afford a pyrrolidinone, and reducing the pyrrolidinone to afford a stereoisomerically preferred 3-aminopyrrolidine derivative.
    Type: Grant
    Filed: June 13, 2000
    Date of Patent: April 3, 2001
    Assignee: Abbott Laboratories
    Inventors: Daniel J. Plata, Steven A. King, Frederick A. Plagge, Anne E. Bailey, Louis Seif
