This review describes the gold-catalyzed reactions of specially activated alkynes, allenes,
and alkenes. Such species are characterized by the presence of either electron-donating or …

Spiro-γ-lactams (spiropyrrolidin-2-ones) are a class of spirocyclic compounds that are
present in a wide range of synthetic bioactive and naturally occurring molecules. The …

Photocatalytic strategies for the preparation of 3-phosphoryl/trifluoromethyl/thiocyanato
azaspiro [4.5] trienones via a radical-initiated cascade annulation reaction of N …

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 …

A palladium-catalyzed asymmetric annulative dearomatization of phenols with butene
dicarbonate is reported, enabling twofold decarboxylative allylation to regioselectively …

The combination of the Ugi reaction and electro-organic synthesis can aid in the creation of
novel heterocycles that have not been previously explored. In this study, a new strategy …

A gold-catalyzed dearomatization reaction of β-naphthol derivatives via intramolecular
hydroalkylation of alkynes is described. In the presence of 5 mol% Au complex, various …

A four‐component reaction of N‐arylpropiolamides, Hantzsch esters, Na2S2O5 and water
via a radical cascade cyclization process with the insertion of sulfur dioxide mediated by …

A palladium‐catalyzed intermolecular dearomative formal [4+ 2] annulation of phenols with
propargyl electrophiles is reported, enabling substituent‐controlled regiodivergent synthesis …

Spirodienone derivatives have unique structural characteristics. Its spiroatoms are
quaternary carbons that act as bridges between dienone and four, five, six and even seven …
