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