Try bifunctional aminophosphines! An asymmetric organocatalytic [4+2] cycloaddition between α‐substituted allenoates and tosylaldimines using bifunctional N ‐acyl aminophosphine catalysts was described (see scheme). This operationally simple catalytic system could provide valuable complementary results to those of the monodentate phosphine system.
