Аннотация:A mild and efficient catalytic enantioselective addition ofindoles to dimethyl arylidenemalonates using MgI2and PyBOXligands bearing halogen substituents has been elaborated. Thereactions were conducted in DCM at low temperature generallyproviding high yields (up to 99%), while enantioselectivity wasshown to be strongly dependent on the nature of substituentsin arylidenemalonate and indole reaching 83% ee. The reactivityof arylidenemalonates under described conditions was foundto be enough different from that in copper-catalyzed Friedel-Crafts alkylation.
