Related Products of 35822-58-3,Some common heterocyclic compound, 35822-58-3, name is 2-Bromobenzaldehyde diethyl acetal, molecular formula is C11H15BrO2, 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: In a 200 mL three necked flask equipped with a dropping funnel, a THF solution of S2 (1.0 equiv.)was slowly added to a mixture of Mg (1.1 equiv., pre-activated by stirring for several hours in vacuo)and THF. A THF solution of alkyne (1.1 equiv.) was subsequently added, and the reaction mixturewas stirred at room temperature. Then, HCl aq. (1M) was added, and the resultant solution wasextracted with Et2O. The organic layer was washed with Brine, dried over anhydrous Na2SO4,filtered, and concentrated in vacuo to yield a crude product including S3. If needed, the purificationwas performed by a column chromatography on a silica gel (eluted with 510% EtOAc/hexane).
The synthetic route of 35822-58-3 has been constantly updated, and we look forward to future research findings.
