With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.31127-39-6,2,3-Dihydrobenzo[b][1,4]dioxine-6-carbaldehyde oxime,as a common compound, the synthetic route is as follows.,31127-39-6
General procedure: A mixture of a’ (10.0 mmol) in CH2Cl2 was stirred at room temperature, NCS (1.60 g, 12.0 mmol) was then added. The resulted mixture was stirred at reflux and propynol (0.56 g, 10.0 mmol) was added dropwise. After 0.5 h, triethylamine (1.01 g, 10 mmol) was added dropwise and refluxed for another 4 h. After cooling, the reaction mixture was washed with water and evaporated under reduced pressure. The obtained residue was purified by silica gel chromatography with petroleum ether/ethyl acetate as eluent to give intermediate b’.
The synthetic route of 31127-39-6 has been constantly updated, and we look forward to future research findings.
