Synthesis of the tricyclic core structure of vindoline
摘要:
An efficient synthesis of the core tricyclic structure (18) of vindoline has been achieved using the strategy, which features an intramolecular 1,3-dipolar cycloaddition of the azido dienone (12) to give aziridine (13) with complete region- and stereocontrol.
