Abstract

Both intermolecular and macrocyclic intramolecular cyclopropanation reactions occur with greater selectivity for the cis-(Z)-diastereoisomer than for the trans-(E)-diastereomer in reactions catalyzed by chiral dirhodium(II) azetidinone-carboxylates; the influence of the catalyst’s ester alkyl group on enantiocontrol is substantial but appears to be delicately balanced by steric factors.
