  • Publication number: 20050239725
    Abstract: The present invention provides a method for synthesizing 1-(acyloxy)-alkyl derivatives from 1-acyl-alkyl derivatives, which typically proceeds stereospecifically, in high yield, does not require the use of activated intermediates and/or toxic compounds and is readily amendable to scale-up. The current invention also provides 1-acyl-alkyl derivatives of known drug components and methods for synthesizing these 1-acyl-alkyl derivatives.

  • Patent number: 6927036
    Abstract: Disclosed is a method for synthesizing 1-(acyloxy)-alkyl derivatives of primary or secondary amine drugs from 1-acyl-alkyl derivatives of primary or secondary amine drugs, which typically proceeds stereospecifically, in high yield, does not require the use of activated intermediates and/or toxic compounds and is readily amenable to scale-up. For example, 1-acyl-alkyl derivatives of gabapentin and pregabalin are oxidized to yield 1-(acyloxy)-alkyl derivatives of gabapentin and pregabalin, respectively.
