Reference of 929-75-9,Some common heterocyclic compound, 929-75-9, name is 1,11-Diamino-3,6,9-trioxaundecane, molecular formula is C8H20N2O3, 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: Diester1 (1mmol) and the appropriate diamine2-6 (1mmol) were dissolved in dry methanol (50mL) and sodium methoxide (2mmol) was added. A mixture was stirring for 72hat room temperature. After completion of the reaction (controlled by TLC), the solvent was evaporated under reduced pressure and the oily residue was purified by column chromatography (1-5% MeOH in CH2Cl2). All the macrocyclic products obtained in this way are colourless solids, stable to air.
The synthetic route of 929-75-9 has been constantly updated, and we look forward to future research findings.
