Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 102359-00-2, name is 2-Oxoindoline-5-carboxylic Acid, A new synthetic method of this compound is introduced below., Application In Synthesis of 2-Oxoindoline-5-carboxylic Acid
General procedure: Compound 7 (2.1 g, 0.012 mol) and HBTU (5.0 g, 0.013 mol) were dissolved in dry DMF, in a 250 ml round bottom flask. DIPEA (6.5 ml, 0.037 mol) was added and the reaction mixtures were stirred for 30 min. L or D- phenylalanine methyl ester hydrochloride (3.0 g, 0.014 mol) or glutamic acid dimethyl ester hydrochloride (3.0 g 0.014 mol) was added and the reaction mixture was kept stirring overnight under ambient conditions. Reaction monitoring by TLC was performed on silica gel plates using CHCl3:MeOH 9:1 as eluent. Saturated NaHCO3 solution (150 ml) was added to the mixture and the precipitate was filtered, washed with saturated NaHCO3 solution and water. The crude product was purified by column chromatography CHCl3:MeOH (95:5) to give the product as white to off-white solid.
The synthetic route of 102359-00-2 has been constantly updated, and we look forward to future research findings.
