Synthesis of 3-arylpyrroles and 3-pyrrolylacetylenes by palladium-catalyzed coupling reactions
摘要:
Efficacious methods for the synthesis of 3-arylpyrroles or 3-pyrrolylacetylenes are described based on the palladium-catalyzed coupling of appropriate 1-(triisopropylsilyl)-3-substituted pyrroles with aryl halides or monosubstituted acetylenes and subsequent tetrabutylammonium fluoride desilylation.
