Procedure

A solution of 1.30 g of 5 in 25 mL of t-butyl alcohol was added to a solution of 30 mL of t-butyl alcohol containing 0.53 g of potassium t-butoxide. The reaction mixture was stirred at room temperature for 1 h, whereupon it was added to 150 mL of ether and 20 mL of H2O. The organic layer was separated and dried over MgSO4, and the solvent was removed by rotary evaporation to afford 0.40 g of racemic RG-4, predominantly the (E)-isomer. 1H NMR δ (ppm) 7.18 (t, CH═CNO2), 5.2 (t, CH3C(CH3)═CH and CH2C(CH3)═CH), 2.19 (s, C═C(CH3)NO2), 2.0 (m, C═CHCH2CH2C(CH3)═CHCH2), 2.2-2.3 (m, CH2C═CNO2), (CH3C═(CH3), 1.6-1.7 (all s, CH3C(CH3)═CHCH2CH2CCH3), 1.2-1.5 (m, CH2CH(CH3)CH2), 0.95 (d, CH2CH(CH3)CH2).
