Advances in understanding the mechanisms of homogeneous nickel catalysis has led to a remarkable progress in this field. However, the discovery of active catalysts is still largely based on trial and error, and the catalysts are mostly based on chelating (nitrogen) ligands. We report a combined theo ...

Arylidene-∆$^2$-pyrrolin-4-ones undergo organocatalyzed double spirocyclization with 3-isothiocianato oxindoles in a domino 1,4/1,2-addition sequence. The products contain three contiguous stereocenters (ee up to 98%, dr up to 99:1, 12 examples). The absolute configuration of the major diastereomer ...
