Electric Literature of 929-75-9, A common heterocyclic compound, 929-75-9, name is 1,11-Diamino-3,6,9-trioxaundecane, molecular formula is C8H20N2O3, 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.
General procedure for the preparation of compounds 10-15 (B) (0016) The appropriate diamines were added to compound 1a and Na2CO3 (2eq.) with stirring in DMF (5mL). The mixture was stirred overnight at room temperature. After completion, as judged by TLC, the solvent was evaporated under reduced pressure. The mixture was resolved in EtOAc and washed twice with water and brine. The organic layer was dried over Na2SO4, then filtered and concentrated. The crude product was purified by column chromatography (CH2Cl2/MeOH, 25/1 v/v) to give the target compound as a white solid.
The synthetic route of 929-75-9 has been constantly updated, and we look forward to future research findings.
