An efficient Mn(III)-promoted cascade reaction of tryptamine-derived isocyanides with arylboronic acids for accessing spiroindoline derivatives is described.
Ag(I)-catalyzed highly diastereoselective construction of divergent spiroindolines via dearomatizing indole-ynone spirocyclization/nucleophile addition cascade reaction is disclosed herein.
Herein, we describe a highly diastereoselective approach for synthesizing polyfunctionalized spiroindolines from indolyl-ynones involving an ipso-iodocyclization/nucleophile addition cascade.
A Rh(III)-catalyzed intermolecular regioselective dearomative spirocyclization of 2-aryl-3-nitrosoindoles with alkynes is described, which provides C2-spiroindolines under mild conditions.
This review focuses on recent advancements in the efficacy of gold catalysts for the cycloisomerisation of ynamides, diynes, and 1,n-enynes to build complex molecules, with critical insight into their mechanism and reaction scope.
