    摘要:
    AbstractHighly selective asymmetric synthesis of 2‐hydroxy fatty acid methyl esters has been accomplioshed through chiral imide enolates. Five chiral oleic acid imides were prepared by reaction of oleioc acid with pivaloyl chloride followed by reaction with five different lithiated chiral oxazolidinones including (R)‐(+)‐4‐benzyl‐2‐, (S)‐(‐)‐4‐benzyl‐2‐, (4R,5S)‐(+)‐4‐methyl‐5‐phenyl‐2‐, (4S,5R)‐(‐)‐4‐methyl‐5‐phenyl‐2‐, and (R)‐(+)‐4‐isopropyl‐2‐oxazolidinones in 88–92% yileds. The chiral imides were reacted with NaN(Me3Si)2 at −78°C to give enolates, which subsequently reacted with 2‐(phenylsulfonyl)‐3‐phenyloxaziridine to give hydroxylated products in 78–83% yields. Methanolysis of the hydroxylated products with magnesium methoxide gave methyl 2‐hydroxyoleate. Enantiomeric excesses (ee) of the products were determined to be very high (98–99% ee) by 1H nuclear magnetic resonance study after esterification of the hydroxy group with (S)‐(+)‐O‐acetylmandelic acid. Enantioselective hydroxylation of other fatty acids including elaidic, petroselinic, vaccenic, and linoleic was evaluated under the similar conditions using (4R, 5S)‐(+)‐4‐methyl‐5‐phenyl‐2‐oxazolidinone as a chiral auxiliary to give 98% ee values for all cases.

    Disclosed are a method for preparing 1-palmitoyl-3-acetylglycerol in high purity and high yield without a purification process using a column chromatography, and a method for preparing 1-palmitoyl-2-linoleoyl-3-acetylglycerol in high purity and high yield using the same as a key intermediate. The method for preparing 1-palmitoyl-3-acetyl glycerol comprises the steps of: forming a reaction mixture including 1-palmitoyl-3-acetyl glycerol of the Formula 1 in the specification by reacting 1-palmitoylglycerol of the Formula 2 in the specification and an acetylating agent; and separating the optically active 1-palmitoyl-3-acetylglycerol by crystallizing the reaction mixture in a saturated hydrocarbon solvent having 5 to 7 carbon atoms.
