Substrate scope studies. aAll reactions carried out at 0.2 mmol scale under the standard conditions, ligand L5 was used unless otherwise noted, generally over 50/1 anti-diastereoselectivity was observed; bThe absolute configurations of 2e, 2l, 2m, 2p, and 2r were assigned by comparison with reported examples, others were by analogy; cTHF as solvent; dCH3CN as solvent.
