Catalytic enantioselective cyclopropanation of styrene derivatives using N-(2',4'-di-tert-butyl) salicylidene-4-amino[2,2]paracyclophane as an asymmetric ligand
The synthesis and resolution of N-(2',4'-di-tert-butyl)salicylidene-4-amino[2.2]paracyclophane and its utilization in the copper catalyzed enantioselective cyclopropanation of aromatic olefins is reported herein. Conversions of up to 90% and enantioselectivities of > 65% have been achieved for selected olefins.
