Fischer indolization of 2-sulfonyloxyphenylhydrazones: A new and practical approach for preparing 7-oxygenated indoles and application to the first synthesis of eudistomidin-A. (Fischer indolization and its related compounds. Part 28)
An efficient method for synthesis of 7-oxygenated indoles was established by Fischer indolization of the phenylhydrazones (10) with a sulfonyloxy group at the ortho-position. This method was applied to the first synthesis of the calmodulin antagonist eudistomidin-A (2).
