Iodonium salts are key intermediates in Pd-catalyzed acetoxylation of pyrroles

A mild, room-temperature Pd-catalyzed acetoxylation of pyrroles with phenyliodonium acetate is described. The acetoxylation was found to proceed via the initial formation of pyrrolyl(phenyl)iodonium acetates, which were converted to acetoxypyrroles in the presence of Pd(OAc)2. The acetoxylation could also be carried out as a one-pot sequential procedure without the isolation of the intermediate iodonium salts.

Direct approach to multi-substituted pyrroles from 2-propynylamine and 1,3-diketone or β-keto ester using Bi(OTf)3 catalyst

Bi(OTf)3was found to be a good catalyst for the direct synthesis of multisubstituted pyrroles from the readily accessible 2-propynylamine and activated methylene compounds in which the bismuth played two roles: σ-and π-activations. Copyright

Investigations into the parallel synthesis of novel pyrrole-oxazole analogues of the insecticide pirate

Investigations into the parallel synthesis of selected analogues of a structurally unique pyrrole-oxazole analogue of the pyrrole insecticide pirate, are reported. Acylaminoketone salts were obtained from ketobromides in moderate to high yields and excell

Novel and direct oxidative cyanation reactions of heteroaromatic compounds mediated by a hypervalent iodine(III) reagent

(Chemical Equation Presented) The hypervalent iodine(III) reagent phenyliodine bis(trifluoroacetate) (PIFA) mediates the selective cyanation reactions of a wide range of electron-rich heteroaromatic compounds such as pyrroles, thiophenes, and indoles unde

N-p-Toluenesulfonylpyrroles from 1,3-dienes

1,3-Dienes can be converted to N-p-toluenesulfonylpyrroles in two steps: 1) [4+2]-cycloaddition with N-sulfinyl-p-toluenesulfonamide and 2) conversion of the 3,6-dihydro-1,2-thiazine oxide adduct to a pyrrole using triethylamine-trimethylphosphite.
