  • Stereoselective amination: Via vinyl-silver intermediates derived from silver-catalyzed carboxylative cyclization of propargylamine

    Sadamitsu Y., Saito K., Yamada T.

    Chemical Communications (Chemical Communications)  56 ( 66 ) 9517 - 9520 2020.08

    ISSN  13597345

     View Summary

    © The Royal Society of Chemistry. The stereoselective synthesis of aminovinyloxazolidinones based on the electrophilic amination of a vinyl-silver intermediate, generated by silver-catalyzed carbon dioxide incorporation on a propargyl amine, was achieved. The geometry of the aminated product was determined by a single crystal X-ray analysis and NOE measurement and it was elucidated that the geometry was proved to be opposite to the geometry predicted from the previous silver-catalyzed carbon dioxide fixation on a propargyl amine derivative. This unexpected stereoselectivity could be successfully explained by a radical mechanism. This journal is

  • Thermal decarboxylative Nazarov cyclization of cyclic enol carbonates involving chirality transfer

    Kozuma A., Komatsuki K., Saito K., Yamada T.

    Chemistry Letters (Chemistry Letters)  49 ( 1 ) 60 - 63 2020

    ISSN  03667022

     View Summary

    © 2020 The Chemical Society of Japan. Decarboxylative Nazarov cyclization of chiral cyclic enol carbonates proceeded to afford chiral 2-cyclopentenones with excellent chirality transfer under thermal conditions without any catalyst. Interestingly, the thermal decarboxylative Nazarov cyclization furnished the desired product with better chirality transfer than the Lewis acid-catalyzed reaction.

  • Silver-Catalyzed Carbon Dioxide Fixation on Alkynylindenes

    Okumura A., Chuang P.Y., Saito K., Yamada T.

    Organic Letters (Organic Letters)   2020

    ISSN  15237060

     View Summary

    © The synthesis of polycyclic indene derivatives via silver-catalyzed carbon dioxide fixation on 2-alkynylindene derivatives was achieved by nucleophilic addition of the indenyl anion to carbon dioxide involving carbon-carbon bond formation and subsequent intramolecular cyclization to the alkyne part activated by a silver catalyst. This cascade process could be applied to various substrates to obtain the corresponding products in high yields. The endo/exo selectivity of the cyclization could be controlled by the steric or electronic effect of the substituents on the substrates, and 6-endo-selective cyclization was realized to afford α-pyrone-fused indenes.

  • Decarboxylative Nazarov Cyclization-Based Chirality Transfer for Asymmetric Synthesis of 2-Cyclopentenones

    Komatsuki K., Kozuma A., Saito K., Yamada T.

    Organic Letters (Organic Letters)  21 ( 17 ) 6628 - 6632 2019.09

    ISSN  15237060

     View Summary

    © 2019 American Chemical Society. Asymmetric synthesis of 2-cyclopentenones was achieved by chirality transfer based on Lewis acid catalyzed decarboxylative Nazarov cyclization of optically active cyclic enol carbonates, which are prepared by silver-catalyzed carbon dioxide incorporation into optically pure propargyl alcohols. The stereochemistry at the 4,5-positions of the 2-cyclopentenones was cleanly constructed by reflecting the stereochemistry of the starting materials. This method could be applied to various substrates to obtain the corresponding products in high yields with highly efficient chirality transfer.

  • Microwave specific effect on catalytic enantioselective reactions

    Yamada T.

    Asia-Pacific Microwave Conference Proceedings, APMC (Asia-Pacific Microwave Conference Proceedings, APMC)  2018-November   1627 - 1629 2019.01

    ISSN  9784902339451

     View Summary

    © 2018 IEICE The microwave specific effect was investigated on the catalytic enantioselective reactions; atropo-enantiveselective ring-opening reaction of biaryl lactones and enantioselective Claisen rearrangement reaction. These reactions were efficiently enhanced with microwave irradiation under reaction temperature control, thought any loss of the enantioselectivities were not detected. It was also found that the racemization rate of the atropo-optically active biaryl lactone was enhanced by microwave irradiation. As these observations could not be explained by the simple thermal effect, microwave specific effect should be considered.

     View Summary

    The effect of circularly polarized microwave irradiation was examined. Substrate was charged, without irradiation, or under right-handed / left-handed CPM irradiation, and the ee of the reduced product was analyzed. When the asymmetric catalysis was irradiated with 12.4 GHz CPM, the ee under the right-handed conditions was improved more than the non-irradiated conditions, but decreased in the left-handed conditions. In the 2.45 GHz / 50 W CPM irradiation to the racemic catalytic reaction, both the right-handed and the left-handed conditions improved, and the microwave effect should be considered.
    The CPM effect on atropo-isomerization reaction was examined. After 2.45 GHz / 20 W CPM irradiation, the ee was analyzed after reduction to prevent from racemization. As a result of the statistical processing, we found reaction conditions that the enantiomeric excess was observed in the opposite directions on the left-handed and the right-handed, though in the racemic 95% confidence interval.
