A New Synthesisof(+/-)Trypargine

A new route for the synthesis of (+/-)-trypargine (I) is described.The Pictet-Spengler reaction of Nb-benzyltryptamine with α-ketoglutaric acid was carried out in aprotic media to afford the key intermediate, 2-benzyl-1,2,3,3-tetrahydro-9H-pyri

ASYMMETRIC SYNTHESIS OF (1S)-(-)-TRYPARGINE

(1S)-(-)-Trypargine 8(1a) was synthesized from (1S,3R)-(-)-2-benzyl-3-(methoxycarbonyl)-1,2,3,4-tetrahydro-9H-pyridoindole-1-propionic acid (3a), prepared by the asymmetric Pictet-Spengler reaction of Nb-benzyl-(D)-tryptophan methyl este
