Related Products of 6346-09-4, A common heterocyclic compound, 6346-09-4, name is 4,4-Diethoxybutan-1-amine, molecular formula is C8H19NO2, 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.
N-Fmoc-4-amino-butyraldehyde diethyl acetal4-Amino-butyraldehyde diethyl acetal (8.0 g, 0.050 mol) was Fmoc protected following Procedure 16 to give the desired N-Fmoc-4-amino-butyraldehyde diethyl acetal (22.08 g, MS m/e [M+Na]+ calcd 406.2, found 406.1), which was carried through to the next step without further purification; Procedure 16: Protection of Amine by Fmoc GroupTo a stirring solution of the amine (0.049 mol) in DCM (100 mL), was added DIPEA (16 mL, 0.099 mol) and the reaction mixture was cooled to O0C. Fmoc- Cl (12.8 g, 0.049 mol) was then added portion-wise over several minutes, and the reaction was allowed to warm to room temperature for 2 hr. The organic layer was washed with water (2 x 50 mL) and brine (50 mL), dried over Na2SO4, filtered and concentrated to dryness to yield the Fmoc protected amine (90-95% yield).
The synthetic route of 6346-09-4 has been constantly updated, and we look forward to future research findings.
