Abstract
A new chiral iron porphyrin-based catalyst performed a-methylstyrene stereoselective cyclopropanation with excellent yields (up to 99%),enantio- and diastereoselectivities (eetrans up to 87%, trans/cis ratios up to 99 : 1) and outstanding TON and TOF values (up to 20 000 and 120 000 h 1 respectively).
