New learning discoveries about 4265-16-1

4265-16-1 Benzo[b]furan-2-carboxaldehyde 61341, abenzofuran compound, is more and more widely used in various.

4265-16-1, Benzo[b]furan-2-carboxaldehyde is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: To a solution of aldehyde 1 (1 equiv.) in tetrahydrofuran (THF) was slowly added 1.0 M allyl magnesium bromide (2 equiv.) at 0 oC. Some of the aldehydes 1f-1m, 1w, and 1x were treated with the solution of zinc and allyl bromide instead of allyl magnesium bromide because allyl magnesium bromide did not work properly. The reaction mixture was warmed to room temperature and stirred for 2-12 h. Saturated NH4Cl aqueous solution was added to the mixture and it was poured into ethyl acetate and extracted with ethyl acetate 2 times. The combined organic layers were washed with brine, dried with Na2SO4, filtered, and concentrated. The residue was purified by silica gel column chromatography (Hexane/Ethyl acetate) to give compounds 2 (26-99% of yield).

Brief introduction of 4265-16-1

As the paragraph descriping shows that 4265-16-1 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4265-16-1,Benzo[b]furan-2-carboxaldehyde,as a common compound, the synthetic route is as follows.

Example 17 4-(Benzofuran-2-ylmethoxy)-2-(2,6-dioxo-piperidin-3-yl)-isoindole-l,3-dioneStep 1 :[211] 2-Benzofurancarbaldehyde (2.2 g, 15 mmol) was dissolved in 25 mL of methanol. To this solution was added sodium borohydride (0.28 g, 7.5 mmol) in small portions over a period of 20 minutes. Then 2 mL of water were added and the mixture was evaporated. The residue was dissolved in ethyl acetate (75 mL) and washed with water (3 x 75 mL), dried (MgSO4) and evaporated, providing 2.1 g of benzofuran-2-yl-methanol, in 95% yield; 1H NMR (CDCl3) delta 2.03 (t, J = 6.1 Hz, IH), 4.77 (d, J = 6.1 Hz, 2H), 6.66 (s, IH), 7.19-7.32 (m, 2H), 7.45-7.50 (m, IH), 7.53-7.57 (m, IH).

As the paragraph descriping shows that 4265-16-1 is playing an increasingly important role.
