Stereoretentive Suzuki–Miyaura couplings of amide 39 and enantioenriched amide 41. Conditions: Ni(cod)2 (5 mol %), 10 (10 mol %), substrate (1.0 equiv), boronate 5 (2.5 equiv), K3PO4 (4.0 equiv), toluene (1.0 M), and H2O (2.0 equiv) heated at 70 °C for 2 h. Yield reflects the average of two isolation experiments. Legend: (a) reaction run at 90 °C for 2 h. Yield determined by 1H NMR analysis using hexamethylbenzene as an external standard.
