A convenient zinc(II) chloride-catalyzed regioselective propargylation/amination/cycloisomerization process has been developed for the synthesis of substituted pyrrole derivatives from propargylic acetates, enoxysilanes and primary amines. Various aromatic and aliphatic propargylic acetates participate well in the reaction, providing the propargylation/amination/cycloisomerization products in g...
متن کاملMolecular iodine- catalyzed convenient synthesis of meso substituted dipyrromethanes
The reaction at room temperature of an aromatic aldehyde with pyrrole in the presence of Iodine, acetic acid catalyzed of meso-substituted dipyrromethane. The mixture was ground together in a mortar with a pestle at room temperature for short reaction time and easy operation under at room temperature. The meso substituted dipyrromethane is purified by crystallization and column chromatography o...
متن کاملPalladium-catalyzed synthesis of N-vinyl pyrroles and indoles.
A stereospecific palladium-catalyzed N-vinylation of azaheterocycles with vinyl triflates is described. Cyclic and acyclic vinyl triflates along with nonnucleophilic azaheterocycles were found to be substrates for this palladium-catalyzed synthesis of N-vinyl pyrrole and indole derivatives.
متن کاملBiomimetic synthesis of 1-aryl-2,5-dimethyl pyrroles using egg white nano-ovalbumin at room temperature under solvent-free conditions
Ovalbumin, as the major component of egg-white, is a globular, biocompatible, nontoxic and biodegradable phosphoglyco protein. This protein with the molecular weight of 44.5 kDa, contains 385 residues of amino acids with isoelectric point (pI) of 4.5. Many purification procedures have been reported for egg-white proteins such as gel permeation and anion exchange chromatography. In this study, w...
