Synthesis of N-Arylindazoles and Benzimidazoles from a Common Intermediate
摘要:
A variety of N-aryl-1H-indazoles and benzimidazoles were synthesized from common arylamino oximes in good to excellent yields The product selectivity depends upon the base used in the reaction, as triethylamine promoted the formation of benzimidazoles, whereas 2-aminopyridine promoted the formation of N-arylindazoles This method is valuable to the synthetic community because both indazoles and benzimidazoles are prevalent in pharmaceuticals

A method is provided for synthesizing 1H-indazole compounds in which aromatic carbonyl compounds are reacted with a nitrogen source to form oximes which are then converted to 1H-indazoles.

An efficient copper-catalyzed method for N-arylation of amines has been developed with part-per-millioncatalystloadings at room temperature under air. Reactions of substituted (E)-1-(2-halophenyl)alkanone oximes with aliphatic amines or aromatic amines provided the N-arylation products in good to excellent yields.
