Substrate scope studies. a,b aAll reactions carried out at 0.2 mmol scale under the standard conditions, ligand L1 was used unless otherwise noted, generally over 50/1 anti-diastereoselectivity was observed; bThe absolute configurations of 3a, 3g, and 3h were assigned by comparison with reported examples and X-Ray single crystal analysis of 6, others were by analogy; cTHF as solvent; dDME as solvent.
