  Synthesis and nucleophilic properties of 1,2-dialkyl-3-nitropyrroles and 1,5-dialkyl-4-nitropyrrole-2-carboxylic acid derivatives

  摘要：

  1,2-Dialkyl-3-nitropyrroles 1 are versatile synthetic tools for obtaining substituted pyrrolidines or fused ring heterocycles such as pyrrolopyridines, pyrrolopyrimidines or pyrroloazepines. We have established a method for obtaining compounds related to structure 1 and studied the reactivity as a nucleophile of the benzylic type moiety in the alkyl residue bound to position 2.

  One 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. The oxidative deacetylation and reductive cyclization of β-ketoesters derived from ethyl acetoacetate and o-nitrobenzyl
