| titleOfInvention | A kind of process for catalytic synthesis of Benzazole compounds |
| abstract | The invention discloses a kind of process for catalytic synthesis of Benzazole compounds, include the following steps：(1) ortho-nitrophenyl ethene or derivatives thereof, connection boric acid pinacol ester, alkali and rudimentary saturated monohydroxy alcohol are stirred into reaction in a nitrogen atmosphere；(2) reaction product of step (1) is cooled to room temperature, adds ethyl acetate and be sufficiently mixed, after filtering, then washed with ethyl acetate；(3) the rudimentary saturated monohydroxy alcohol in the organic phase of the material obtained by spinning step (2), crosses silicagel column, then elutes above-mentioned silicagel column with the eluant, eluent being made of petroleum ether and ethyl acetate, obtains purified product, i.e., described Benzazole compounds.The process for catalytic synthesis of the present invention is in neutral conditions, raw material is used as by the use of cheap connection boric acid pinacol ester, solvent is used as using friendly rudimentary saturated monohydroxy alcohol, Benzazole compounds are obtained by shirtsleeve operation, low raw-material cost is easy to get, efficient, security is good, has extensive expansion and good prospects for commercial application. |
