25021-08-3, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.25021-08-3, name is 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid. An updated downstream synthesis route of 25021-08-3 as follows.
200 mg (0.594 mmol) of tert-butyl (14-amino-3,6,9,12-tetraoxatetradec-1-yl)carbamate, 111 mg (0.713 mmol) of (2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid and 410 mul (2.4 mmol) of N,N-diisopropylethylamine were dissolved in 6 ml of dimethylformamide, and 339 mg (0.892 mmol) of HATU were added. The reaction mixture was stirred at RT for 1 h and purified directly by preparative RP-HPLC (column: Reprosil 250¡Á30; 10mu, flow rate: 50 ml/min, MeCN/water, 0.1% TFA). The solvents were evaporated under reduced pressure and the residue was dried under high vacuum. This gave 130 mg (43% of theory) of tert-butyl [17-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-16-oxo-3,6,9,12-tetraoxa-15-azaheptadec-1-yl]carbamate. LC-MS (Method 1): Rt=0.71 min; MS (ESIpos): m/z=474 (M+H)+.
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid
