We report an example of non‐dearomative trifunctionalizing ipso‐spirocyclization of
unactivated alkenes through photoredox‐catalyzed, nitrogen‐radical‐triggered cyclization …

Photo-mediated radical dearomatization involving 5-exo-trig cyclizations has proven to be
an important route to accessing spirocyclic compounds, whereas 6-exo-trig spirocyclization …

We describe a catalyst, oxidant, and coupling‐reagent free strategy to access 4‐membered
heterocycles, representing a unique example of visible‐light triggered intramolecular …

Herein, we report a fully atom-economic and highly step-economic cascade dearomatization
with non-activated phenyl and other hetero-aryl rings for access to aniline-tethered spiro …

The cleavage of an unactivated aryl nitro group triggered by alkyl radicals enables a
dearomative cyclization, affording diversified alkylated spiro [5.5] trienones in good yields …

A novel photoredox catalysis for multiple functionalization of two different types of
unactivated alkenes in a single operation was reported through a conceptually new mode of …

A photocatalytic tandem cyclization of o-alkenylbenzaldehydes using pyridinium salts as the
amination reagent is described. A variety of valuable seven-membered nitrogenous …

Indole-ynones have been established as general substrates for radical dearomatizing
spirocyclization cascade reactions. Five distinct and varied synthetic protocols have been …

A de novo method for direct construction of cyclopenta [b] indolines via a photocatalytic
fluoroalkylative radical cyclization cascade of ynamides has been established, which …

The development of green and sustainable approaches for the synthesis of small molecules
is always in demand. Oxetanes and azetidines are strained heterocycles that possess …
