  Stereochemistry and total synthesis of janolusimide, a tripeptide marine toxin

  摘要：

  The stereochemistry of janolusimide, a lipophilic tripeptide marine toxin, has been fully elucidated by stereoselective synthesis of the lactam component (5S)-3,3'-dimethyl-5-isopropylpyrrolidin-2,4-dione. The peptide was then synthesized in 13 steps and in 0.8% total yield. (C) 2000 Elsevier Science Ltd. All rights reserved.
