Novel Synthesis of Nitrogen Heterocycles Using Zirconium-Promoted Reductive Cyclization
摘要:
Perhydroindole derivatives were prepared from enynes using zirconium-promoted reductive cyclization. The zirconacycles derived from enynes 1 were treated with iodine, isonitriles, oxygen, and carbon monoxide to give various heterocycles. The carbon-zirconium bonds of the zirconacycle could be selectively cleaved by different reagents.
