Front Cover: Deoxygenative Intramolecular Minisci-Type Reaction to Access Fused Heterocyclic Scaffolds (Eur. J. Org. Chem. 7/2023)

Herein, we present a straightforward strategy for the synthesis of fused heterocycles through a deoxygenative, intramolecular Minisci-type reaction. This approach grants access to complex polycyclic scaffolds in three steps from readily available starting materials, such as chlorinated heteroarenes and 1,3-diols. The use of saccharide derivatives as the starting 1,3-diol motif allows for the synthesis of novel heterocyclic scaffolds with excellent diastereoselectivity and formal retention of configuration at the newly formed C−C bond.
