Scope of varied alkyl chain length substrates. Reactions were run on a 0.10 mmol scale. Isolated yields are reported, and enantiomeric ratios were determined by chiral HPLC (see the Supporting Information for details).NsNHOPiv was used as the nitrogen source.MsNHOPiv was used as the nitrogen source.(R,R)-8 was used as the precatalyst.Reaction was run at 60 C.
