Autotandem catalysis: Synthesis of pyrroles by gold-catalyzed cascade reaction
A novel synthesis of substituted pyrroles by a gold(I)-catalyzed cascade reaction has been developed. The reaction proceeded with an autotandem catalysis consisting of an initial addition of gold-acetylide to an acetal moiety and was followed by gold-catalyzed 5-endo-dig cyclization and aromatization. Gold catalysts play a dual role in activating nucleophilicity or electrophilicity of terminal acetylenes by forming gold-acetylides or by pi-coordination. The formal (3 + 2) annulation of two components provided a variety of substituted pyrroles in a modular fashion.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 224311-51-7 is helpful to your research., Synthetic Route of 224311-51-7
