In this study, Rh(III)‐catalyzed C−H bifunctionalization and direct vinylene annulation of sulfoxonium ylides and N‐carbamoylindoles with vinylene carbonate was accomplished, which afforded a series of naphthalenones containing a β‐ketosulfoxonium ylide moiety, isocoumarins, and pyrimidones. This protocol featured mild conditions, broad substrate scope, and functional‐groups compatibility. In addition, related applications and preliminary mechanistic exploratory were also investigated
The indazolones directed chemoselective synthesis of 8H-indazolo [1,2-a]cinnolines have been realized via cascade Cp*Ir(III)- and Cp*Rh(III)-catalyzed C-H activation/cyclization reaction of 1-arylindazolones with sulfoxonium ylides. The strategy showcased broad substrate scope,...
Herein, we report a Rh(III)-catalyzed C4-selective activation of indoles by using iodonium ylides as carbene precursors. This protocol proceeded under redox neutral reaction conditions and provided important coupling products bearing...
The
indole-substituted trifluoromethyl sulfonium ylide
has been
developed via Cp*Rh(III)-catalyzed diazo-carbenoid addition to trifluoromethylthioether
and is the first example of an Rh(III)-catalyzed diazo-carbenoid addition
reaction with trifluoromethylthioether. Several kinds of indole-substituted
trifluoromethyl sulfonium ylide were constructed under mild reaction
conditions. The reported method exhibited high functional group compatibility
and broad substrate scope. In addition, the protocol was found to
be complementary to the method disclosed by a Rh(II) catalyst.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
