  • Patent number: 6977303
    Abstract: The present invention relates to highly enantiomerically pure lactam-substituted propanoic acid derivatives and methods of making and using therefor. The invention involves a multi-step synthesis to produce the lactam compounds. In one step of the reaction sequence, asymmetric hydrogenation of a lactam-enamide was performed to produce an intermediate that can ultimately be converted to a series of pharmaceutical compounds. The invention also contemplates the in situ synthesis of an intermediate of the multi-step synthesis, which provides economic advantages to the overall synthesis of the lactam compounds.

  • Patent number: 6909019
    Abstract: A process is disclosed for preparing aldehydes by isomerization of the corresponding unsaturated primary alcohols using a transition metal catalyst system, in an alcoholic solvent and in the presence of an acid. An aldehyde forms by isomerizing an unsaturated primary alcohol under conditions that protect the newly formed aldehyde as a dialkylacetal in situ during the reaction. Protecting the aldehyde as an acetal allows for facile separation of the product from the catalyst as well as effectively driving the reaction toward completion.
