  摘要：

  The synthesis of N(b)-benzyl-2-(dimethyl 2-malonyl)- and 2-(methyl 2-acetyl)tryptamines (21, 25) provides access to methyl 4-(3-furanyl)-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole-5-carboxylate (12) and methyl 3-benzyl-5-(3-furanyl)-2,3,3a,4,5,7-hexahydro-1H-pyrrolo[2,3-d]carbazole-6-carboxylate (9), potential intermediates for the syntheses of strychnos alkaloids. A new condensation-sigmatropic rearrangement reaction gives the tetracyclic product 9 directly from the tryptamine 25.

  tryptophan-derived benzyl 2-(benzylamino)-3-[3-[2-[(methoxycarbonyl)methyl]indolyl]]propionate gave tetracyclic hexahydro-1H-pyrrolo[2,3-d] intermediates with stereoselective placement of substituents for cyclization to pentacyclic Strychnos alkaloids. The benzyl ester moiety was readily removed by formation of a corresponding nitrile and reduction, thus providing enantioselective syntheses of the tetracyclic

  Enantioselective syntheses of (-)-lochneridine (1) and (-)-epi-lochneridine (2) were obtained by two alternative C-20 diastereoselective syntheses of the respective pentacyclic (3aS,5S,11bR)-methyl 12-oxo-3,5-ethano-2,3,3a,4,5,7-hexahydro-3H-pyrrolo[2,3-d]carbazole-6-carboxylate ((-)-8) and tetracyclic methyl (2S,3aS,5R,11bR))-3-benzyl-2,3,3a,4,5,7-hexahydro-5-(2-(1-butenyl))-1H-pyrrolo[2,3d]carbazole-6-carboxylate ((-)-12b) precursors from tryptophan derived 2-[(methoxycarbonyl)methyl]3-[2(S)-(methoxy or benzyloxycarbonyl)-2-(N-b-benzyl)aminoethyl]indole (15 or 16). While a modified Grignard reaction of the ketone (-)-8 provided (-)-lochneridine (1), dihydroxylation and cyclization of the olefin (-)-12b gave its C-20 epimer (2).

  Reaction of N(b)-benzyl-2-[(methoxycarbonyl)methyl]tryptamine (3) with 4,4-dimethoxybut-2-en-1-al (6) provided, by a new condensation-electrocyclization reaction, the tetracyclic core 2 of strychnine (1). A 13-step elaboration of this compound gave a stereoselective synthesis of the racemic alkaloid.
