Well-defined Cu() complexes based on [N,P]-pyrrole ligands catalyzed a highly endoselective 1,3-dipolar cycloaddition

We herein report the synthesis and catalytic application of a new family of dinuclear Cu( i ) complexes based on [N,P]-pyrrole ligands. The Cu( i ) complexes ( 4a - d ) were obtained in good yields and their catalytic properties were evaluated in the1,3-dipolar cycloaddition of azomethine ylides and...

Summary:We herein report the synthesis and catalytic application of a new family of dinuclear Cu( i ) complexes based on [N,P]-pyrrole ligands. The Cu( i ) complexes ( 4a - d ) were obtained in good yields and their catalytic properties were evaluated in the1,3-dipolar cycloaddition of azomethine ylides and electron-deficient alkenes. The air-stable complexes 4a - d exhibited high endo-diasteroselectivity to obtain substituted pyrrolidines, and the catalytic system showed excellent reactivity and wide substitution tolerance. We report the synthesis of a family of air-stable dinuclear Cu( i ) complexes based on [N,P]-pyrrole ligands that exhibited high endo-diasteroselectivity in the 1,3-dipolar cycloaddition reaction of azomethine ylides and electron-deficient alkenes.
