A study of 2-aminofurans was written by Lythgoe, David J.;McClenaghan, Ian;Ramsden, Christopher A.. And the article was included in Journal of Heterocyclic Chemistry in 1993.COA of Formula: C8H5NO3 This article mentions the following:
Catalytic reduction of 2-nitrofurans, e.g., I, gives low yields of 2-aminofurans 1 which are not isolated but are trapped using Et ethoxymethylenecyanoacetate (6) or ethoxymethylenemalononitrile (7). In these reactions 2-aminofuran (1a) behaves like a dieneamine with substitution occurring at position 5 of the ring. When the 5-position is substituted reaction takes place at position 3 and thermal cyclization of the product gives furo[2,3-b]pyridine derivatives, e.g., II. An AM1 calculation of the properties of 2-aminofuran (1a) is reported and the results are consistent with observed properties. In the experiment, the researchers used many compounds, for example, 2-Nitrobenzofuran (cas: 33094-66-5COA of Formula: C8H5NO3).
2-Nitrobenzofuran (cas: 33094-66-5) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.COA of Formula: C8H5NO3
