Direct and Highly Diastereoselective Synthesis of Azaspirocycles by a Dysprosium(III) Triflate Catalyzed Aza-Piancatelli Rearrangement

Ring the changes: The first example of an intramolecular aza‐Piancatelli rearrangement is reported. Dysprosium(III) trifluoromethanesulfonate efficiently catalyzes the synthesis of functionalized azaspirocycles in a trans‐selective manner by a 4π electrocyclization of elaborated furylcarbinols (see...
