Synthesis of (S)-Vasicol and (S)-3-Hydroxy-2-pyrrolidinone
摘要:
Starting from (S)-malic acid, a flexible approach to (S)-3-hydroxy-2-pyrrolidinone and (S)-1-alkyl-3-hydroxy-2-pyrrolidinones was reported. Using this method, the first total syntheses of (-)-vasicol as well as deaminovasicol were accomplished, which allowed the revision and clarification the confusion about the structure of naturally occurring (-)-vasicol.

three‐steps method for the conversion of N‐benzyl (S)‐3‐hydroxypyrrolidin‐2‐one 6 to (2S,3S)‐3‐hydroxyproline 1 is reported. The key step is the reductive cyanation of 6. The synthesis of 1 constitutes a formal asymmetricsynthesis of (2S,3S)‐3‐hydroxyproline betaines 2.
