Synthesis of N-benzylated indole-, indazole- and benzotriazole-4,7-diones
摘要:
The benzylation of 4,7-dimethoxy-1H-indole (5) followed by an oxidative demethylation led to 1-benzyl-1H-indole-4,7-dione (2) with a 73% overall yield. From the commercially available 7-nitro-1H-indazole (7), a three-step pathway was developed to access 1-benzyl-1H-indazole-4,7-dione (3). Two of these steps were investigated in order to improve the process. The direct synthesis of 1-benzyl-1H-benzotriazole-4,7-dione (4), through a 1,3-dipolar cycloaddition between benzyl azide and para-benzoquinone (13), was also studied. The simplicity of the methodologies described offers wide perspectives in obtaining 1-alkylated indole-, indazole- and benzotriazole-4,7-diones. (c) 2006 Elsevier Ltd. All rights reserved.
