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. 2436-29-5, name is 3-(1,3-Dioxoisoindolin-2-yl)propanal, A new synthetic method of this compound is introduced below., HPLC of Formula: C11H9NO3
General procedure: Neat TiCl4 (120 muL, 1.1 mmol) was added dropwise to a solution of the corresponding alpha-silyloxy methyl ketone (1.0 mmol) in CH2Cl2 (5.0 mL) at -94 C, and the mixture was stirred for 5 min. Then, anhydrous i-Pr2NEt (190 muL, 1.1 mmol) was added dropwise and the resulting dark red solution was stirred for 30 min at -94 C. After dropwise addition of the freshly distilled aldehyde (1.5 mmol), stirring was continued for 30 min at -78 C. The reaction was quenched by the addition of saturated NH4Cl (5 mL) and vigorously stirred at room temperature for 10 min. Then it was diluted with Et2O (50 mL), and washed with H2O (50 mL), saturated NaHCO3 (50 mL) and brine (50 mL). The combined organic extracts were dried (MgSO4) and concentrated. The resulting crude was analysed by 1H NMR and purified by column chromatography.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
