Related Products of 2436-29-5,Some common heterocyclic compound, 2436-29-5, name is 3-(1,3-Dioxoisoindolin-2-yl)propanal, molecular formula is C11H9NO3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
ally:3L reaction flask was added dichloromethane 800mL, Et2NH (175.5mL, 1.68mol, 2.1eq), K2CO3 (121.6g, 0.88mol, 1.1eq), a mechanical stirrer, nitrogen atmosphere, was cooled to 0 deg.] C, was added dropwise over 25 minutes 3- [2- (1,3-diketo isoindoline)] propanal (162.55g, 0.80mol, 1.0eq) dissolved in 800mL DCM solution was added dropwise to 0 stirred for 5 minutes, then at room temperature for 3 hours.After concentrating the solvent was filtered off portion, the filtrate was concentrated dryness to give 199.93g crude D2, crude yield: 97%.(Instability resulting intermediate, required stored at -20 ).
The synthetic route of 2436-29-5 has been constantly updated, and we look forward to future research findings.
