Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 929-75-9, name is 1,11-Diamino-3,6,9-trioxaundecane, A new synthetic method of this compound is introduced below., Product Details of 929-75-9
Step 4. Synthesis of 11-t-butoxycarbonylamino-3,6,9-trioxaundecylamine 3 g of 1,11-diamino-3,6,9-trioxaundecane obtained in the above step 3 was dissolved in 5 mL of tetrahydrofuran, and then a solution of 1.14 of di-t-butyl dicarbonate in 5 mL of tetrahydrofuran was added dropwise under ice cooling. Then, the solution was stirred overnight at room temperature, and concentrated under reduced pressure. The residue was dissolved in ethyl acetate, and then the solution was washed with saturated saline. The organic layer was dried, and then concentrated under reduced pressure. The residue was purified with silica gel column chromatography to obtain 1 g of the objective compound.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
