Ni(II)-catalyzed enantioselective Nazarov cyclizations.

Irene Walz1, Antonio Togni.   

Abstract

Nazarov cyclizations are catalyzed by a dicationic Ni(II) complex containing the chiral tridentate phosphine Pigiphos; the catalyst exerts a high degree of torquoselectivity and affords the products in up to 88% ee.
