In order to prepare 2- (3-aminophenyl) -5-aminobenzoxazole, there are many synthesis methods.
can start from aniline compounds containing corresponding substituents, and construct benzoxazole structures through cyclization. For example, specific substituents are modified for aniline first, the desired group is introduced at a suitable position, and then the cyclization reagent is used to promote the cyclization and condensation of amino groups with ortho-hydroxyl groups (or groups that can be converted to hydroxyl groups) under suitable reaction conditions to form benzoxazole rings, thereby obtaining the target product. < Br >
Or starting from the parent structure of benzoxazole, the 2- (3-aminophenyl) and 5-amino groups can be gradually introduced through electrophilic substitution, nucleophilic substitution and other reactions. Moderately active halogenated aromatics and amino-containing nucleophiles can be used to undergo nucleophilic substitution in the presence of bases to introduce 3-aminophenyl groups into the 2-position of benzoxazole; subsequently, similar methods or other suitable amination strategies can be used to introduce amino groups at the 5-position.
can also be achieved by the reaction catalyzed by transition metals. For example, in a palladium-catalyzed cross-coupling reaction, a benzopazole derivative containing a suitable functional group is coupled with an aryl halide or other electrophilic reagent to precisely construct the carbon-carbon bond and carbon-nitrogen bond of the target molecule, thereby completing the synthesis of 2- (3-aminophenyl) -5-aminobenzopazole. In the reaction, factors such as catalyst dosage, reaction temperature, reaction time and solvent need to be strictly controlled to improve the reaction yield and selectivity.
