A new synthetic route of 2436-29-5

Synthetic Route 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.

Synthetic Route 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.

3-(1,3-Dioxoisoindolin-2-yl)propanal (2.5 g, 12.3 mmol) was dissolved in 80 mL of DCM. (1ethoxycarbonylethylidene)triphenylphosphorane (4.50 g, 12.9 mmol) was added thereto, and the mixtue was stirred at room temperaturefor 2 hours. The reaction solution was concentrated under reduced pressure and purified by column chromatography toobtain the title compound (2.99 g, 89 %).1H-NMR (CDCl3) delta7.83 (2H, m), 7.72 (2H, m), 6.91 (1H, m), 5.90 (1H, d), 4.16 (2H, q), 3.83 (2H, t), 2.60 (2H, m), 1.26 (3H, t)

The synthetic route of 2436-29-5 has been constantly updated, and we look forward to future research findings.
