In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 16800-68-3 as follows. Formula: C10H9NO2
General procedure: A 10 mL glass tube equipped with a stirring bar was charged with the isatin-derived N-Boc ketimine 1 (0.44 mmol, 1.2 equiv), the N-acetylindolin-3-one 2 (0.4 mmol, 1.0 equiv), catalyst 4o (0.02 mmol, 2 mol%) and CH2Cl2 (4.0 mL). The resulting solution was stirred at r.t. for the indicated time. The solvent was then evaporated to give the crude product, which was directly purified by flash chromatography (n-pentane/EtOAc, 4:1 to 1:1) to provide the desired products 3a-t.
According to the analysis of related databases, 16800-68-3, the application of this compound in the production field has become more and more popular.
