Abstract
A novel Cu-mediated rearrangement reaction based on bisamides containing a thiazolidine substructure opens the possibility for diastereoselective synthesis toward a tricyclic annulated and bridged heterocyclic system. The required precursors are easily synthesizable by a two-step synthetic pathway using the concept of sequential multicomponent reactions, i.e. the Asinger and Ugi reactions. Due to this synthesis strategy, a number of unique tricyclic heterocycles, characterized by high diversity, are synthesized in an effective manner.
