Reference of 3676-85-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3676-85-5, name is 5-Aminoisoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 4- aminophthalimide (1 .2 mmol), 2,6-dichlorobenzenesulfonyl chloride (1 .2 mmol), trimethylamine (1.4 mmol), and DMAP (cat.) in toluene was heated at 100 C for 72 h. The reaction mixture wasquenched with H20 and extracted with EtOAc. The combined organic layers was dried overNa2SO4 and filtered. Purification via preparative HPLC gave compound 116 in 3% yield. ?HNIVIR(400 1VIHz, DMSO-d6) 11.75 (s, 1H), 11.22 (s, 1H), 7.74 (d, J= 8.1 Hz, 1H), 7.71 -7.64 (m,2H), 7.59 (dd, J= 8.9, 7.1 Hz, 1H), 7.48 -7.36 (m, 2H). ?3C NIVIR (101 MHz, DMSO) 169.04,169.01, 135.08, 135.04, 134.91, 132.60, 127.08, 125.13, 122.59, 111.35.
The synthetic route of 5-Aminoisoindoline-1,3-dione has been constantly updated, and we look forward to future research findings.
