    Enantiospecific photochemical 6π-ring closure of α-substituted atropisomeric acrylanilides–role of alkali metal ions

    Direct irradiation of atropisomeric α-substituted acrylanilides in the presence of alkali metal ions gave high ee values in the 3,4-dihydro-2-quinolin-2-one photoproduct, while in the absence of alkali metal i...

    Enantiospecific 6π-photocyclization of atropisomeric α-substituted acrylanilides in the solid-state: role of crystalline confinement on enantiospecificity

    Direct irradiation of optically-pure axially-chiral α-substituted acrylanilides in the crystalline state leads to 3,4-dihydro-2-quinolin-2-one photoproduct with an enantiomeric ratio of 85: 15 while a racemic ...

    6π-Photocyclization of O-tert-butylacrylanilides. N-substitution dictates the regiochemistry of cyclization

    O-tert-Butylacrylanilides with N–H substitution undergo 6p-photocyclization at the unsubstituted orthocarbon, whereas the corresponding N-methyl derivatives cyclize at the orthocarbon bearing the tert-butyl with ...
