Electric Literature of 112656-95-8, 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. 112656-95-8, name is 7-Nitroindoline-2,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
7′-Nitro-spiro[1,3-dioxolan-2,3′-indol]-2′(1’H)-one (1b) was obtained as grey powder with yield 64%, m.p. 207-208 C [Found C 50.78, H 3.55, N 11.79. C10H8N2O5 requires C 50.85, H 3.41, N 11.86%]; numax (KBr) 1119, 1322, 1346, 1465, 1528, 1630, 1762, 3219 cm-1; deltaH (400.1 MHz, DMSO-d6) 4.30-4.40 (4H, m, -O-(CH2)2-O-), 7.24 (1H, dd, J 7.2, 8.6, -CH-CH-CH-C-); 7.77 (1H, dd, J 0.6, 7.2, -CH-CH-CH-C-), 8.12 (1H, dd, J 1.0, 8.6, -CH-CH-CH-C-), 11.17 (1H, s, NH); deltaC (100.6 MHz, DMSO-d6) 66.4, 123.3, 126.9, 131.6; MS (EI, 70 eV): m/z (I, %): 236 (41, M+), 219 (96), 208 (46), 191 (100), 175 (22), 161 (20), 147 (29), 131 (11), 117 (58), 106 (12), 90 (29), 75 (26), 63 (30), 43 (19), 30 (60).
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, 7-Nitroindoline-2,3-dione, other downstream synthetic routes, hurry up and to see.
