  • Patent number: 6608214
    Abstract: This invention provides a novel process for producing optically active 3-hydroxy-&ggr;-butyrolactone in a short step, which is superior economically and in efficiency and industrially suitable by using a starting material which is inexpensive and easily available and reagents easy to handle. This invention relates to a process for producing optically active 3-hydroxy-&ggr;-butyrolactone represented by formula I: wherein the symbol * means an asymmetric carbon atom, which comprises hydrogenating an optically active 4-substituted oxy-3-hydroxybutyrate represented by formula II: wherein R1 represents a C1-4 lower alkyl group, R2 represents a protective group for a hydroxyl group deprotected by hydrogenation with a heterogeneous hydrogenation catalyst, and the symbol * has the same meaning as defined above, in the presence of a heterogeneous hydrogenation catalyst and an acidic substance followed by deprotection and simultaneous ring closure thereof.

  • Patent number: 6593478
    Abstract: A new, more efficient and highly stereospecific process is described for the preparation of compounds with general formula (R)-(I) and of absolute configuration (R), where the groups M, W, Q and Q1 are as defined in the description, starting from compounds of absolute configuration (S) by hydrolysis, in the presence of acids, of the corresponding esterified derivatives. The (R)-(I) products obtained with the process described herein are chiral synthons useful for the production of enanthiomerically pure drugs. The preparation of (R)-carnitine is also provided.

  • Publication number: 20030065196
    Abstract: This invention affords a solution to the technical problem of obtaining one or both enantiomers of 5-substituted 4-hydroxyfuran-2-ones in pure form by resolution with enantiomerically pure bases. Racemic mixtures of 5-substituted 4-hydroxy-2(5H)-furanones, including 5-substituted and 5,5-disubstituted, 4-hydroxy and 3,4-dihydroxy furanones are separated into pure enantiomers by crystallization with an enantiomerically pure base, such as cinchonidine. In specific solvent mixtures, for example, 95% ethanol, the diastereomerically pure salt of one enantiomer crystallizes. The enantiomerically pure furanone can then be obtained simply by filtration and treatment of the salt with an acid, for example, trifluoracetic acid, followed by precipitation with water, filtration and drying. Moreover, the other enantiomer may be equally obtained in pure form by evaporation of the mother liquor, followed by the same treatment of the salt as described before.

  • Patent number: 6541646
    Abstract: The invention relates to a method for producing compounds of general formula (I) wherein R1 is selected from the following groups: (a) OR5 and (b) mono-, di-, or tri-substituted phenyl; and R2 represents a group (C1-C6) alkyl. The method is characterized in that it comprises the following steps: a) reacting a compound of general formula (III) with an acid of general formula R1CH2 COOH (III) in a water-free medium; b) reacting the resulting compound with a strong base in an aprotic solvent in order to obtain an intermediate cyclic compound which forms a compound of general formula (I) after dehydration; and c) isolating said resulting compound of general formula (I).
