An efficient method for construction of various 3,4,5-trisubstituted phenols has been achieved via Rh(III)-catalyzed coupling of phosphoniums with internal alkynes. This protocol showed good substrate compatibility as an array of...

A rhodium-catalyzed formal [4+1]-cyclization reaction of aryl substituted pyrazoles with cyclopropanols via C–H bond activation/cyclization processes to selectively construct a series of carbonyl functionalized pyrazolo[5,1-a]isoindoles is described. The reaction features...
