AB Enantioselective organocatalysis has become a prominent area of interest in syntheticchemistry, offering new tools for the development of more efficient synthetic methodologies.Although sulfide-catalyzed reactions have been reported for the formation of 3-memberedrings their use in higher-order cycloadditions remains unexplored. In this work, severalenantioselective sulfide-catalyzed higher-order cycloadditions between (aza)heptafulvenesand different bromides were studied. Three chiral sulfide catalysts were specificallysynthesized for this study. While the reaction with methyl bromocrotonate as a substrateafforded different cycloadducts under catalytic conditions, bromoacetophenones were foundto undergo a non-catalyzed pathway.
