  Synthesis of (S)-γ-Lactones with a Combination of Lipase-Catalyzed Resolution and Mitsunobu Reaction

  摘要：

  Six kinds of (S)--lactones [e.g., (S)--decalactone, (S)--undecalactone, and (S)--jasmolactone] were synthesized with 71-88% yields and 97% optical purities by combining lipase-catalyzed resolution with the Mitsunobu reaction.

  Chiral -lactones of both enantiomers were synthesized with more than 90% optical purities. The key step was Novozym 435-catalyzed hydrolysis of racemic N-benzyl-4-acetoxyalkylamides. Additionally, because (R)--lactones are predominant in apricot, mango, peach, passion fruit, and strawberry, synthesis was attempted using only one enantiomer selectively. The (R)-enantimer was synthesized with more than 80% total yield and more than 90% optical purity by a combination of Novozym 435-catalyzed hydrolysis and the Mitsunobu reaction.
