Abstract
Enantioselective [2+ 2]-photocycloaddition reactions on 4-(2'-aminoethyl) quinolones in solution were studied using the enantiomerically pure complexing agent 1 as source of chirality. The intermolecular reactions of fully N-protected substrates 5a-5c with different 2- alkyl-substituted acrylates 12-15 represent the first systematic study on the diastereoselectivity of their intermolecular [2+ 2]-photocycloadditions to unsymmetrically 1, ...
