Deacetylation of indoles

WebThe rate constants of acetylation of several pyrroles, indoles, and carbazoles by the Vilsmeier–Haack reagent (NN-dimethylacetamide–carbonyl chloride) have been measured in 1.2-dichloroethane at 25 °C.Most substrates undergo N-substitution and the data strongly support a mechanism involving rate determining direct attack on the nitrogen atom.. The … WebOne pot syntheses of furan, thiophene, and pyrrole were accomplished by oxidative deacetylation using Mn ( III )/Co ( II) catalysts and the Paal–Knorr reaction from 1,5-dicarbonyl compounds, which are prepared from the conjugate addition of ethyl acetoacetate to α,β-unsaturated carbonyl compounds.
