    Microwave-assisted Solvent-free Intramolecular 1,3-Dipolar Cycloaddition Reactions Leading to Hexahydrochromeno[4,3-b] pyrroles: Scope and Limitations

  • Original language description

    We report the microwave-assisted solvent-free synthesis of hexahydrochromeno[4,3-b]pyrroles. Intramolecular 1,3-dipolar cycloadditions proceed under these conditions within 15 to 40 min in 16-90% yields. An influence of the microwave irradiation upon various [3+2] cycloaddition reaction intermediates was studied. Additionally, a scope and limitations of these reactions including an influence of the dipolarophile geometry upon the cycloaddition selectivity and steric demands of the dipole upon its reactivity were also disclosed. These observations led us to postulate a preferable transition state of the reaction. Finally, an influence of the microwave irradiation to the isomerization of activated olefins was also described.

    Mikrovlnami podporované intramolekulární 1,3-dipolární cykloadiční reakce v postředí bez rozpouštědla vedoucí k hexahydrochromeno[4,3-b]pyrrolům: rozsah a omezení

  • Czech description

    Popisuje se mikrovlnami podporovaná bezrozpouštědlová syntéza hexahydrochromeno[4,3-b]pyrrolů. Za těchto podmínek probíhají intramolekulární 1,3-dipolární cykloadice v čase 15 - 40 min s výtěžky 16-90%. Byl sledován vliv mikrovln na různé intermediáty [3+2]cykloadicí. Dále byl sledován rozsah použití a omezení těchto reakcí včetně vlivu geometrie dipolarofilu na selektivitu a vlivu sterické náročnosti dipolu na reaktivitu. Tímto způsobem se nám podařilo formulovat transitní stav reakce. Dále byl sledován vliv mikrovln na isomeraci aktivovaných olefinů.
