Related Products of 929-75-9, These common heterocyclic compound, 929-75-9, name is 1,11-Diamino-3,6,9-trioxaundecane, its 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.
0.500 g of cinnamic acid, 0.295 g of 1,11-diamino-3,6,9-trioxadecane, 0.647 g of EDCI, 0.037 g of DMAP, 10 mL of anhydrous dichloromethane were sequentially added to the round bottom flask, and stirred at room temperature. After 12 h, 20 mL of dichloromethane was added, and the mixture was washed successively with brine (1×30 mL) and water (2×30 mL), dried over anhydrous sodium sulfate, filtered, evaporated to dryness Chloroform/methanol = 35:1; 50:4) gave 0.178 g of a pale yellow oily substance, yield 28% (see Figure 49 for the synthetic route and Figure 50 for the characterization)
Statistics shows that 1,11-Diamino-3,6,9-trioxaundecane is playing an increasingly important role. we look forward to future research findings about 929-75-9.
