  • Asymmetric Total Synthesis of (−)-Alkaloid 223A and Its 6-Epimer
    作者:Xiaotao Pu、Dawei Ma
    DOI:10.1021/jo0341261
    日期:2003.5.1
    gamma-amino alcohols 7 and 18 are prepared by using the diastereoselective Michael addition of lithium N-benzyl (R)-alpha-methylbenzylamide to alpha,beta-unsaturated esters as a key step. The Michael addition of 7 or 18 to an alkynone 8 followed by an intramolecular cyclization afford the cyclic enamine 10 or 20, which are subjected to the diastereoselective hydrogenation, and the subsequent transformations

    then replaced by an N-(tert-butoxycarbonyl) group and O-debenzylation and oxidation gave the carboxylic acid 70 that corresponds to the C(1)–C(18) fragment of pamamycin 607 (1). Similar chemistry was used to prepare the C(1′)–C(11′) fragment 89 of the pamamycin, except that in this case the configuration of the secondary alcohol introduced by the allylstannane reaction had to be inverted using a Mitsunobu
    发现在路易斯酸存在下,使用苯基烯基或邻苯二甲酰亚胺,由氯化锡(IV)介导的(Z)-均烯丙基醇的环化反应,然后还原性去除苯基烯基,可得到具有优异立体控制的2,5-顺式-二取代四氢呋喃。 。使用该程序,通过(IV)立体选择性地制备了(2 S,4 S,8 R,6 Z)-9-苄氧基-2-叔丁基二苯基甲硅烷基氧基-8-甲基非-6-烯-4-醇(11))之间的化物促进反应(R)-5-苄氧基-4-甲基戊-2-烯基(三丁基)烷(3)和(S)-3-叔丁基二苯基甲硅烷基氧基丁醛(10),得到(2 S,3 R,6 S,8 S)-1脱后的-苄氧基-8-叔丁基二苯基甲硅烷氧基-3,6-环氧-2-甲基壬烷(13)。将该四氢呋喃选择性地脱保护,氧化和酯化,得到非乳酸甲酯(2)。已经建立了2,5-顺式-二取代的四氢呋喃的这种合成,将其用于完成帕马霉素607(1)的合成。(2 S,3 R从(R)立体选择性地制备,6S,8R)-1-苄氧基-8-
  • Studies towards the enantioselective synthesis of 5,6,8-trisubstituted amphibian indolizidine alkaloids via enaminone intermediates
    作者:Joseph P. Michael、Charles B. de Koning、Christiaan W. van der Westhuyzen
    DOI:10.1039/b418062c
    日期:——
    Investigations aimed at the enantioselective total synthesis of indolizidine 223A, a recently described 5,6,8-trisubstituted indolizidine alkaloid from a dendrobatid frog, are described. tert-Butyl (2R,3R)-3-amino-2-ethylhexanoate and its (2S,3R)-diastereomer, prepared in several steps from lithium N-benzyl-N-[(1R)-1-phenylethyl]amide and tert-butyl (2E)-hex-2-enoate by the Davies protocol, served as chiral building blocks from which two complementary suites of diastereomeric intermediates were made en route to pivotal tert-butyl 3-[2-(alkoxycarbonylmethylene)pyrrolidin-1-yl]-2-ethylhexanoate intermediates 20 and 21. Cyclisation of these enaminones, achieved by acid hydrolysis of the tert-butyl esters and activation of the liberated carboxylic acids as mixed anhydrides, afforded 6-ethyl-7-oxo-5-propyl-1,2,3,5,6,7-hexahydroindolizine-8-carboxylate esters 28 and 29. Several further transformations of these potential scaffolds for the synthesis of the target alkaloidal systems are also reported.

  • Formal Synthesis of (5R,8R,8aS)-Indolizidine 209I via Enaminones Incorporating Weinreb Amides
    作者:Joseph P. Michael、Charles B. de Koning、Darren L. Riley
    DOI:10.3987/com-08-s(d)68
    日期:——
    A formal enantioselective synthesis of the amphibian alkaloid (5R,8R,8aS)-(-)-indolizidine 2091 (6) is reported. Control or the absolute, stereochemistry at C-5 resulted from application of the Davies procedure, which entails stereoselective conjugate addition of (R)-(+)-N-benzyl-1-phenylethylamine to tert-butyl (E)-hex-2-enoate. The resulting chiral adduct 26 was converted in eight steps into a pivotal enaminone incorporating a Weinreb amide, the inherent nucleophilicity of which was exploited in a cyclisation that yielded the key bicyclic intermediate (5R)-N-methoxy- N-methyl-5-propyl-1,2,3,5,6,7-hexahydroindolizine-8-carboxamide (38). Stereoselective catalytic hydrogenation of the alkene bond, reaction of the Weinreb amide with ethylmagnesium bromide, and epimerisation of the resulting ketone completed the formal synthesis of the target alkaloid.
