    • Typical Experimental Procedure for Samarium Diiodide Mediated Coupling A stirred and carefully deoxygenated solution of the corresponding nitrone (0.5 mmol) in dry THF (5 mL) was cooled to -78°C under argon. Methyl acrylate and H2O were degassed by boiling under a stream of argon for 20 min. Methyl acrylate (0.7 mmol, H2O (4 mmol, and a solution of SmI2 (15 mL of 0.1 M in THF, 1.5 mmol) were then added. The temperature was kept at -78°C until the reaction was judged to be complete by TLC (2 h, whereupon a sat. aq solution of Na2S2O 3 (40 mL) was added. The mixture was extracted with EtOAc (4 x 30 mL) and the combined organic layers were washed with brine, dried over MgSO 4, filtered, and concentrated in a rotatory evaporator. The residue was purified by silica gel column chromatography using EtOAc-hexanes 1:2
