Highly congested spiro-compounds via photoredox-mediated dearomative annulation cascade

Communications Chemistry, 2022
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 has been much less explored.

Photoredox-Catalyzed Synthesis of 3-Sulfonylated Pyrrolin-2-ones via a Regioselective Tandem Sulfonylation Cyclization of 1,5-Dienes

Molecules, 2023
A mild, visible-light-induced, regioselective cascade sulfonylation-cyclization of 1,5-dienes with sulfonyl chlorides through the intermolecular radical addition/cyclization of alkenes C(sp2)-H was developed.

Oxidative Radical Cyclization–Cyclization Reaction Leading to 1H-Benzo[f]isoindole Derivatives

Molbank, 2017
The synthesis of 1H-benzo[f]isoindole derivatives was achieved by the cascade radical cyclization–cyclization reaction of the active methine substrate having an allyl group and phenyl group as different two radical acceptors.

Self-Terminating, Oxidative Radical Cyclizations [PDF]

Molecules, 2004
The recently discovered novel concept of self-terminating, oxidative radical cyclizations, through which alkynes can be converted into carbonyl compounds under very mild reaction conditions using O-centered inorganic and organic radicals as oxidants, is ...

Oxidative radical ring-opening/cyclization of cyclopropane derivatives

Beilstein Journal of Organic Chemistry, 2019
The ring-opening/cyclization of cyclopropane derivatives has drawn great attention in the past several decades. In this review, recent efforts in the development of oxidative radical ring-opening/cyclization of cyclopropane derivatives, including ...

Síntese de 2-iodobenzamidas e 3-(iodoacetamido)benzamidas ligadas à D-galactose e suas reações de carbociclização radicalar mediadas por hidreto de tri-n-butilestanho Synthesis of 2-iodobenzamides and 3-(iodoacetamido)benzamides linked to D-galactose and their tri-n-butyltin hydride-mediated radical carbocyclization reactions

Química Nova, 2009
Starting from methyl 6-O-allyl-4-azido-2,3-di-O-benzyl-4-deoxy-α-D-galactopyranoside, four new derivatives containing 2-iodobenzamido and 3-(iodoacetamido)benzamido groups were synthesized.
