  • Configuration of the Psymberin Amide Side Chain
    作者:Sezgin Kiren、Lawrence J. Williams
    DOI:10.1021/ol0508375
    日期:2005.7.1
    structure of the amide side chain of psymberin, a potent and selective cytotoxin, is proposed. Syn and anti models of the amide side chain were prepared, and the structural assignment was confirmed by X-ray crystallographic analysis of the anti isomer. Comparison of (1)H and (13)C NMR data establishes homology between the natural product and the synthetic model compound of anti configuration and not the corresponding

  • Studies toward the Unique Pederin Family Member Psymberin: Full Structure Elucidation, Two Alternative Total Syntheses, and Analogs
    作者:Yu Feng、Xin Jiang、Jef K. De Brabander

    日期:2012.10.17
    Two synthetic approaches to psymberin have been accomplished. A highly convergent first generation synthesis led to the complete stereochemical assignment and demonstrated that psymberin and irciniastatin A are identical compounds. This synthesis featured a diastereoselective aldol coupling between the aryl fragment and a central tetrahydropyran core and a novel one-pot procedure to convert an amide, via intermediacy of a sensitive methyl imidate, to the N-acyl aminal reminiscent of psymberin. The highlights of the second generation synthesis include an efficient iridium-catalyzed enantioselective bisallylation of neopentyl glycol and a stepwise Sonogashira coupling/cycloisomerization/reduction sequence to construct the dihydroisocoumarin unit. The two synthetic avenues were achieved in 17-18 steps (longest linear sequence, similar to 14-15 isolations) from 3 fragments prepared in 7-8 (first generation) and 3-8 (second generation) steps each. This convergent approach allowed for the preparation of sufficient amounts of psymberin (similar to 0.5 g) for follow-up biological studies. Meanwhile, our highly flexible strategy enabled the design and synthesis of multiple analogs, including a psymberin pederin hybrid, termed psympederin, that proved crucial to a comprehensive understanding of the chemical biology of psymberin and related compounds that will be described in a subsequent manuscript.
  • Synthesis and Complete Stereochemical Assignment of Psymberin/Irciniastatin A
    作者:Xin Jiang、Jorge García-Fortanet、Jef K. De Brabander
    DOI:10.1021/ja0537068
    日期:2005.8.1
    We describe a concise and flexible synthetic avenue for the preparation of compounds with structures relevant to those proposed for the novel marine-derived differential cytotoxins psymberin and irciniastatin A. Our efforts led to their complete stereochemical assignment and the notion that psymberin and irciniastatin A are identical compounds. Our total synthesis features an interesting termini-differentiating
