YieldReaction ConditionsOperation in experiment
74% General procedure: n-BuLi (4.0 mL of a 2.5 M solution in n-hexane, 10.0mmol) was added to a solution of octyltriphenylphosphonium bromide (4.55 g, 10.0 mmol) in anhyd THF (30 mL) at ?82 °C under N2 atmosphere. Themixture was stirred for 30 min at ?82 °C and then a solutionof CPDT-4-one 7 (1.48 g, 7.69 mmol) in anhyd THF (30mL) was added. After stirring for an additional 30 min at this temperature, the mixture was allowed to reach r.t. Thereaction was quenched with H2O and the aqueous layer wasextracted with Et2O. After drying the combined organiclayers over MgSO4, removal of the solvents in vacuo, andpurification by column chromatography (SiO2, petroleumether), a yellow oil was obtained (1.64 g, 74percent). 1H NMR(300 MHz, CDCl3): delta = 7.27 (d, J = 4.7 Hz, 1 H), 7.13 (d,J = 4.8 Hz, 1 H), 7.12 (d, J = 4.8 Hz, 1 H), 7.08 (d, J = 4.9Hz, 1 H), 6.44 (t, J = 7.8 Hz, 1 H), 2.68 (q, J = 7.5 Hz, 2 H),1.62 (quint, J = 7.4 Hz, 2 H), 1.23?1.48 (m, 8 H), 0.89 (t, J= 6.8 Hz, 3 H).
