A Mild, Diastereoselective Construction of Cyclic and Spirocyclic Ketals Employing a Tandem Photoisomerization/Cyclization Tactic
[Image: see text] The cyclization of trans-δ-hydroxy enones to cyclic mixed ketals routinely requires superstoichiometric strong acid. By operating under a photoisomerization regime, the cyclization of trans-δ-hydroxy enones proceeds under catalytic Brønsted acid to provide cyclic ketals or unsatura...
