  Total Synthesis and Stereochemical Revision of (+)-Aeruginosin 298-A

  摘要：

  [GRAPHICS]Novel routes toward both enantiomers of the bicyclic proline surrogate 2-carboxy-6-hydroxyoctahydroindole, i.e., Choi, were developed on the basis of the oxidative cyclization of L-tyrosine. Synthesis of the proposed sequence of (+)-aeruginosin 298-A did not provide the natural product. Incorporation of a D-leucine residue, in contrast, led to the total synthesis of this thrombin inhibitor.

  Influence of Base and Structure in the Reversible Covalent Conjugate Addition of Thiol to Polycyclic Enone Scaffolds

  摘要：

  The energetics of thiol addition and elimination reactions to bicyclic enones derived from an indole core structure were explored using H-1 NMR and density functional theory (DFT) calculations. The agreement between experiment and theory is excellent, and the combined results reveal that even minor changes in the conformation of the enone, substituents on the scaffold, and the use of different bases have a signficant influence on product distribution. A potential application of these principles is in the rational design of new reversible covalent enzyme inhibitors.

• Asymmetric Total Synthesis of the Stemona Alkaloid (-)-Stenine
  作者：Peter Wipf、Yuntae Kim、David M. Goldstein

  DOI：10.1021/ja00150a010

  日期：1995.11

  Stenine can be extracted from the roots of the Chinese medicinal plant Stemona tuberosa (Stemonaceae), and its structure and absolute configuration were derived by comparison to the major Stemona alkaloid tuberostemonine. We report the first enantioselective total synthesis of (-)-stenine by a strategy that takes advantage of a diastereoselective end-group-differentiating cyclization in the oxidation of L-tyrosine, The resulting cis-fused indolone is converted to the trans-fused core of stenine upon reduction of a pi-allylpalladium complex, and by stereoselective introduction of four additional stereocenters, a butyrolactone and an azepine ring are attached to this alkaloid building block.
• Asymmetric Total Syntheses of Tuberostemonine, Didehydrotuberostemonine, and 13-Epituberostemonine
  作者：Peter Wipf、Stacey R. Spencer

  DOI：10.1021/ja044280k

  日期：2005.1.1

  Detailed experimental approaches toward the pentacyclic Stemona alkaloids tuberostemonine and didehydrotuberostemonine and the close analogue 13-epituberostemonine are described. The syntheses originate with a hydroindolinone derivative that can be obtained on a large scale in a single step from carbobenzoxy-protected L-tyrosine. Highlights of the conversion of this hydroindolinone to the target structures are the three-fold use of ruthenium catalysts, first in azepine ring-closing metathesis and then in alkene isomerization and cross-metathesis propenyl-vinyl exchange, as well as the stereoselective attachment of a y-butyrolactone ring to a tetracycle core structure by use of a lithiated asymmetric bicyclo[3.2.1]octane (ABO) ortho ester. Structural analysis by density functional theory (DFT) methods revealed that the ease of oxidation of the natural product is likely due to the conformational preferences of the pyrrolidine and the fused cyclohexane rings.
• Stereodivergent routes from tyrosine to the 7-(R) and 7-(S) diastereomers of the 7-hydroxy-2,3,7,7a-tetrahydroindole ring found in gliotoxin
  作者：Todd C Henninger、Michal Sabat、Richard J Sundberg

  DOI：10.1016/0040-4020(96)00871-x

  日期：1996.11

  Two routes from the oxidative cyclization product 1 derived from tyrosine to methyl 7-(tert-butyldimethylsiloxy)-N-(benzyloxycarbonyl) -2,3,7,7a-tetrahydroindole-2-carboxylate are described. The routes are stereodivergent leading to the 2-S,7-S,7a-S (6) and 2-S,7-R,7a-S-(13) diasteromers. The former stereochemistry corresponds to that present in gliotoxin.
