Methods for catalytically constructing of N–N axially chiral scaffolds have garnered significant attention since such compounds are widely present in natural products, bioactive molecules, and organic materials. Herein, we report a highly diastereoselective enantioselective organocatalyzed [4 + 1] annulation method synthesizing diverse valuable isoindolinones that possessing axial central chiralities. This methodology uses phosphoric acid as bifunctional catalyst to promote cascade sequence involving two nucleophilic additions, dehydration, dearomatization processes. Control experiments DFT calculations revealed possible mechanism which the stereoselectivity-determining step is likely involve irreversible formation hydroxy biaryl intermediate. Additionally, preliminary biological activity studies showed some these potential suppressing tumor-cell proliferation. attention. Here, authors
