Related Products of 696-41-3,Some common heterocyclic compound, 696-41-3, name is 3-Iodobenzaldehyde, molecular formula is C7H5IO, 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.
Reference Example 136 tert-butyl ({4-(2-fluorophenyl)-5-[(3-formylphenyl)thio]-1,3-thiazol-2-yl}methyl)methylcarbamate To a solution of 2-ethylhexyl 3-{[2-{[(tert-butoxycarbonyl)(methyl)amino]methyl}-4-(2-fluorophenyl)-1,3-thiazol-5-yl]thio}propanoate (749 mg) in ethanol (10 mL) was added sodium ethoxide (381 mg) at 0 C., and the mixture was stirred at room temperature for 4 hr, and concentrated under reduced pressure. A mixture of the residue, 3-iodobenzaldehyde (489 mg), tris(dibenzylideneacetone)dipalladium(0) (35 mg) and 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthine (81 mg) in toluene (10 mL) was stirred at 80 C. for 3 hr. The reaction mixture was allowed to cool to room temperature, water was added, and the mixture was extracted with ethyl acetate. The extract was washed successively with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=4:1) to give the title compound as a yellow oil (676 mg, yield quantitative). 1H-NMR (CDCl3) delta: 1.47 (9H, brs), 3.00 (3H, brs), 4.69 (2H, brs), 7.10-7.20 (3H, m), 7.34-7.50 (3H, m), 7.65-7.68 (2H, m), 9.90 (1H, s).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Iodobenzaldehyde, its application will become more common.
