Standard reaction conditions: 1a (0.75 mmol, 3.0 eq), 2 (0.25 mmol, 1.0 eq), Pd(MeCN)2(OTs)2 (0.019 mmol, 7.5 mol%), ligand (0.023 mmol, 9 mol%), DMA (3 mL), 3Å Ms (50 mg), O2 (1 atm), rt, 24 h. Yields of isolated 3, >20:1 E-alkene product. Enantioselectivty determined by SFC equiped with a chiral stationary phase.
Yields are a combination of 3 and 4, >20:1 E-alkene product.
