  • Syntheses of Strychnan- and Aspidospermatan-Type Alkaloids. 10. An Enantioselective Synthesis of (−)-Strychnine through the Wieland−Gumlich Aldehyde
    作者:Martin E. Kuehne、Feng Xu
    DOI:10.1021/jo9813989
    日期:1998.12.1
    Condensations of L-tryptophan-derived 2-[(methoxycarbonyl)methyl]-3-[2(S)-(benzyloxycarbonyl)- 2-(N-b-benzylamino)ethyl]indole (6) with 4,4-dimethoxyacrolein or with 2,4-hexadienal, followed by removal of the tryptophanyl ester function, respectively gave the tetracyclic acetal (-)-methyl (2S, 3aS,5R,11bR)-3-benzyl-2,3,3a,4,5,7-hexahydro-5-(dimethoxymethyl)-1H-pyrrolo[2,3-d]carbazole-6-carboxylate (10) or the tetracyclic olefin (-)-methyl (2S,3aS,5R,11bR)-3-benzyl-2,3,3a,4,5,7-hexahydro-5-(1-propenyl)-1H-pyrrolo[2,3-d]carbazole-6-carboxylate (14). Their respective hydrolysis or oxidation provided, enantioselectively, the tetracyclic aldehyde (-)-methyl (2S,3aS,5R,11bR)3-benzyl-2,3,3a,4,5,7-hexahydro-5-formyl-1H-pyrrolo[2,3-d]carbazole-6-carboxylate (5). Its reaction with tri-n-butyl-1-(ethoxy)ethoxymethyltin and n-butyllithium, followed by oxidation of the resultant alcohol (-)-methyl (2S,3aS,5R,11bR)-3-benzyl-2,3,3a,4,5,7-hexahydro-5-(1 xi-hydroxy-2-((1-ethoxy-ethoxy))ethyl-1H-pyrrolo[2,3-d]carbazole-6-carboxylate (16) and cyclization furnished the pentacyclic ketone (-)-methyl (2S,3aS,5R,11bR)-3-benzyl-2,3,3a,4,5,7-hexahydro-3,5-ethano-12-oxo-1H-pyrrolo-2,3-d]carbazole-6-carboxylate (15). A Horner-Emmons condensation led to the unsaturated esters (-)-methyl (2S,3aS,5R,11bR)-3-benzyl-2,3,3a,4,5,7-hexahodro-3,5-ethano-12-(E and Z)-[(methoxycarbonyl)-methylene]-1H-pyrrolo[2,3-d]carbazole-6-carboxylates(19 and 20) with 17:1 E/Z selectivity. Reductions of the ester and vinylogous urethane functions in 19 led to the Wieland-Gumlich aldehyde 3 as a 6:1 anomeric hemiacetal mixture. Its condensation with malonic acid provided (-)-strychnine (1) in 5.3% overall yield and 14 steps from the tryptophan derivative 6.
  • Total Synthesis of (−)-Strychnine
    作者:Yosuke Kaburagi、Hidetoshi Tokuyama、Tohru Fukuyama
    DOI:10.1021/ja046407b
    日期:2004.8.1
    Total synthesis of (-)-strychnine is described. Notable features of our synthesis include (1) palladium-catalyzed coupling of the indole and vinyl epoxide moieties, (2) synthesis of the nine-membered cyclic amine derivative from the diol precursor in a one-pot procedure, and (3) transannular cyclization of the nine-membered cyclic amine.
    描述了 (-)-马钱子碱的全合成。我们合成的显着特征包括(1)吲哚和乙烯基环氧化物部分的钯催化偶联,(2)在一锅法中从二醇前体合成九元环胺衍生物,以及(3)跨环环化九元环胺。
