497-25-6, Oxazolidin-2-one is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
497-25-6, General procedure: A steel autoclave-reactor containing substrate 1 or 6 (5 mmol or 10 mmol for 2 or 9) was filled with liquid TFE at r.t. by one third of volume and cooled to 5 C. DNP (1.19 g, 11 mmol) was placed into an auxiliary dosing vessel, which was then closed and filled with the same fluid TFE by half. The obtained DNP solution was slowly added to the reactor (temperature increase of more than 5 C is to be avoided during reagent addition). The dosing vessel was twice washed with the fluid TFE (one third of volume) to transfer residual DNP into the reactor. The reaction mixture was stirred at r.t. at 6 bar for the time given in Table 1. Once the nitration was completed, the autoclave was cooled to 5 C and liquid ammonia (1.3 mL, 50 mmol) was gradually added with intensive stirring by a syringe pump at a flow-rate of 0.1-0.2 mL/min (temperature increase of more than 10 C is to be avoided during reagent addition). The reaction mass was stirred at r.t. for 20 min. Then the fluid and the excess of ammonia were removed via decompression and the autoclave was opened.
As the paragraph descriping shows that 497-25-6 is playing an increasingly important role.
