DIAZONAPHTHOQUINONES: SYNTHESIS, REACTIONS AND APPLICATIONS

This review deals with synthesis and reactions of diazonaphthoquinones during the past 6 years. Various substituted diazonaphthoquinones have been prepared by the reaction of the appropriate naphthol and 2-azido-1,3-dimethylimidazolinium chloride (ADMC) in short direct pathway. This method is likely to find wide spread uses in organic synthesis and material chemistry such as for preparing photoresists. In this review, different metal catalyzed reactions are investigated and applied successfully to the synthesis of important aromatic compounds. In addition, total synthesis of some natural compounds has been attempted using this recently developed diazotransfer methodology. It is hoped that this compilation, in combination with the previously published literatures on diazo-transfer reaction, will provide useful, up-to-date and comprehensive foundation and reference sources for individuals interested in the same field.
