Regioselective synthesis of substituted tropones and azulenes using anodic oxidation of cycloheptatriene systems as the key reaction
摘要:
Regioselective synthesis of di- and trisubstituted tropones has been attained by utilizing anodic oxidation of cycloheptatriene systems as the key reaction. This anodic oxidation has also been found to be useful for the regioselective synthesis of mono- and disubstituted azulenes.
