Ti(Oi-Pr)4-promoted photoenolization Diels–Alder reaction to construct polycyclic rings and its synthetic applications
Abstract
Anthracenols with multiple chiral centres are common motifs in natural products. Here, the authors show a highly stereoselective photoenolization/Diels–Alder methodology involving a key Lewis acid reagent enabling the efficient construction of a family of anthracenol derivatives with quaternary centers.
