Abstract
The bicyclic isoxazolidine scaffolds are the ubiquitously recurring motifs in alkaloids. Despite of their facile biosynthesises in nature, the laboratory synthesis of these derivatives is still complicated. In this paper, the isoxazolidine derivatives are concisely constructed in one process with excellent stereoselectivity from simple tertiary amines through a C–H activation-retro-aza-Michael-oxidation-cyclization tandem sequence by means of visible-light. This protocol provides a concise approach to dactylicapnosinine derivatives.
