Bifunctional N-Acyl-Aminophosphine-Catalyzed Asymmetric [4+2] Cycloadditions of Allenoates and Imines

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 resul...

Zusammenfassung: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.
