Reaction Conditions

Reaction Steps

Lawesson's reagent (119.3 mg, 0.3 mmoles) is added to a stirred solution of futoenone (200 mg, 0.59 mmoles) in toluene (4 ml). The reaction is heated to 60° C. in an oil bath for 2-3 h. TLC of the reaction mixture shows almost complete conversion of starting material. The reaction turns from a green to violet upon heating. The reaction is concentrated in vacuo and purified by MPLC on silica gel using ethyl acetate. A purple foam (154.2 mg, 73.5%) forms upon drying in vacuo. M+(CI)=357. 1H NMR ppm: 0.59 (3H, d), 1.72 (1H, t), 2.07 (1H, m), 2.21 (1H, d), 2.30 (1H, m), 2.43 (1H, m), 2.58 (1H, m), 3.71 (3H, s), 5.08 (1H, t), 5.46 (1H, s), 5.92 (2H, s), 6.65 (4H, m).
