Name is N1,N2-Dimethylethane-1,2-diamine, as a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, and cas is 110-70-3, its synthesis route is as follows.
beta-CD-OTs (500.0 mg, 0.388 mmol) was dissolved in 5 mL dry DMF with 100 mg NaI. N,N?-Dimethylethane-1,2-diamine (1.28 mL, 11.72 mmol) was then added under N2 and the reaction mixture was stirred overnight at 70 C. under N2. The next day the reaction mixture was cooled and precipitated in 50 mL acetone, giving a white precipitate. Unreacted tosylate was removed via the same ion-exchange methods as described above for beta-CD-NH2. Yield=374 mg (80.0%). 1H NMR (300 MHz, D2O, delta): 5.02-4.87 (s, 7H, C1H of CD), 3.93-3.64 (m, 29H, C2H, C3H, C4H, and C5H of CD and NH), 3.61-3.29 (m, 14H, C6H of CD), 3.01-2.36 (m, 10H, N1-CH2, N2-CH2, and N2-(CH3)2).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of N1,N2-Dimethylethane-1,2-diamine, 110-70-3
