The discovery and application of dearomative cascade photocatalysis as a strategy in complex molecule synthesis is described. Visible-light-absorbing photosensitizers were used to (sequentially) activate a 1-naphthol derived arene precursor to divergently form two different polycyclic molecular scaffolds through catalyst selective energy transfer.

An efficient three-component domino reaction among oxa(aza)bicyclic alkenes, sodium azide, and primary haloalkanes is reported, which offers a mild access to 1,2,3-triazolines in an aqueous medium with excellent diastereoselectivities and yields. Further studies show that, water-promoted isomerization of oxa(aza)bicyclic alkenes can afford 1-naphthol derivatives in good yields. Water not only promotes
Taking advantage of the synergy between photocatalysis and cobaloxime catalysis, the keto–enol radical cation of 1-tetralones becomes compatible with the transformation of various 1-tetralones into α-naphthols and H2 by virtue of the continuous-flow approach without any sacrificial oxidants under unusually mild conditions.
