Route of Synthesis (ROS)
| Conditions | Yield |
| With dinitrogen pentoxide In carbon dioxide at 0 – 5℃; under 45004.5 – 60006 Torr; for 1h; liquid CO2; Experimental Procedure General procedure: General nitration procedure.12-14 A steel autoclave (25 cm3) equippedwith sapphire windows containing urethane 1c or amide 3 or 5 (10.0 mmol)was filled with liquid CO2 to 60 bar pressure and cooled to 0 °C. ThenN2O5 (2.4 g, 22.0 mmol) solution in liquid CO2 (~ 4 g) cooled to 0-5 °Cwas gradually pressed out from an auxiliary high-pressure cell by a freshCO2 flow (2 g min-1) to the reaction autoclave. During the addition, thepressure in the latter raised up to 80 bar. The reaction mixture was stirredat 0-5 °C for the time specified in Table 1. Then, CO2 was removed bydecompression and the residue was poured onto ice water (50 ml). Theresulted suspension was extracted with EtOAc (4 × 20 ml), the combinedorganic extracts were washed successively with saturated aqueous NaHCO3(2 × 20 ml) and water (25 ml) and dried over anhydrous Na2SO4. Thesolvent was removed under reduced pressure to afford corresponding nitrocompounds 2, 4 (see Table 1). Compounds 2a,b and 7 were synthesizedby similar procedures using 1.2 g (11.0 mmol) or 6.0 g (55 mmol) ofN2O5, respectively. | 93% |
