Reference of 88150-75-8, The chemical industry reduces the impact on the environment during synthesis 88150-75-8, name is Ethyl 4-(2-(1,3-dioxoisoindolin-2-yl)ethoxy)-3-oxobutanoate, I believe this compound will play a more active role in future production and life.
2-Cyanoethyl 4-(2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)ethoxy)-3-oxobutanoate Ethyl 4-(2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl) ethoxy)-3-oxobutanoate (8g, 25mmoles) and 3-hydroxypropionitrile (12g, 170mmoles) were heated at 100 under N2 for 10 hours in toluene (100ml) containing a catalytic amount of 4-methylphenylsulphonic acid. Ethyl acetate and water were added; the organic layer was separated, washed with water, dried (MgSO4) and the solvent evaporated. Chromatography on silica eluding with ethyl acetate/petroleum ether (60-80) mixtures gave the title ester (8.9g). M/e 345 M+1+; NMR delta (CDCl3) 4.14 (s,2H), 3.53 (s,2H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Ethyl 4-(2-(1,3-dioxoisoindolin-2-yl)ethoxy)-3-oxobutanoate, other downstream synthetic routes, hurry up and to see.
