Reactions of acyl-aminoquinone tosylhydrazones. II. A simple synthesis of 5-substituted indazoloquinones.
摘要:
Indazoloquinone (4) or 5-substituted indazoloquinones (5a-c) were obtained with an acid-catalyzed substitution reaction of mono-(2a-c) or diaminoquinone tosylhydrazones (3a-c) in high yields. The reaction mechanism and rate were investigated.
