Indium(III) Chloride-Catalyzed Propargylation/Amination/Cycloisomerization Tandem Reaction: One-Pot Synthesis of Highly Substituted Pyrroles from Propargylic Alcohols, 1,3-Dicarbonyl Compounds and Primary Amines
propargylation/amination/cycloisomerization tandem process has been developed for the synthesis of highly substituted pyrroles derivatives from propargylic alcohols, 1,3-dicarbonylcompounds and primary amines using indium(III) chloride as a multifunctional catalyst. This method provides a flexible and rapid route to substituted pyrroles.
A mild and efficient AgSbF6-catalyzed synthesis of fully substituted pyrroles through a sequential propargylation/amination/cycloisomerization reaction
fully substitutedpyrroles via a sequential propargylation/amination/cycloisomerization was accomplished using AgSbF6 as a catalyst. The one-pot three-componentreaction of propargylic alcohols, 1,3-dicarbonyl compounds, and primary amines proceeds at a mild temperature, which prevents the formation of furan by-product. The reaction was also successfully applied to the more basic aliphatic amines with
