We report herein an alternative method for the synthesis of seleno-dibenzocycloheptenones
and seleno-spiro [5.5] trienones through the radical cyclization of biaryl ynones in the …

Base-promoted cyclization of 3-organoselenyl-methylene-2-alkynyl aryl propargyl ethers
has been developed for the synthesis of 3-butylselanyl-methylene benzofurans, 3-methyl-2 …

An iron-catalyzed dearomative spirocyclization of biaryl ynones with sodium metabisulfite
and cycloketone oxime esters is developed. By using sodium metabisulfite as the source of …

An efficient and novel approach to accessing 3-selenylquinolines from diaryl diselenides
and acyclic, selenium-free substrates is described. Preliminary mechanistic studies indicate …

Organoselenium compounds are important structures in medicinal chemistry, materials
chemistry and biochemistry. Many drugs contain heterocyclic skeletons. The selenation of …

A new copper-catalyzed radical-triggered fluoromethylation-spirotricyclization of enediyne-
and enyne-nitrile-containing para-quinone methides (p-QMs) was reported for the first time …

Copper-or silver-catalyzed cascade radical addition/dearomative spirocyclization of biaryl
ynones with fluoroalkyl bromides or diethylphosphite has been realized for the first time. This …

This paper describes a selenium-promoted electrophilic cyclization of arylpropiolamides
allowing the synthesis of 3-organoselenyl spiro [4, 5] trienones via a 5-endo-dig ipso-mode …

A fast selenylative spirocyclization of indolyl ynones mediated by PIFA has been developed.
This transformation was enabled by the reactive RSeOCOCF3 species generated in situ …

A novel and green route has been developed for the electrochemical synthesis of spiro [4.5]
trienones through radical‐initiated dearomative spirocyclization of alkynes with diselenides …
