    • Preparation of Penta-2,4-dienenitrile (5) Potassium tert-butoxide (11.76 g, 104.8 mmol) in anhydrous THF (150 mL) was added dropwise to diethyl cyanomethylphosphonate (16.95 g, 95.76 mmol) in anhydrous THF (180 mL) at-78°C After 30 min, freshly distilled acrolein (6.00 g, 108 mmol) was added dropwise. The reaction mixture was stirred for 20 min and then warmed to r.t. and quenched with sat. aq NH4Cl solution. The solution was extracted with Et2O, washed with brine and H2O, and dried (MgSO4, The combined organic layers were concentrated on a rotary evaporator at r.t. and the residue was chromatographed on neutral alumina (hexanes-Et2O, 3:1) to afford 5 (3.974 g, 53, as a mixture of E/Z isomers (80:20, determined by NMR integration, 1H NMR (300 MHz, CDCl3, δ (E-isomer, 7.00 (dd, J, 15.9, 10.8 Hz, 1 H, 6.42 (dt, J, 16.9, 10.8 Hz, 1 H, 5.61 d
