MARJANI, Ahmad Poursattar; KHALAFY, Jabbar  e  AKBARZADEH, Somayeh. Synthesis of Indeno[1,2-b]benzofurans using TPAB as Highly Efficient and Recoverable Catalyst. S.Afr.j.chem. (Online) [online]. 2019, vol.72, pp.160-163. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2019/v72a21.

Herein we report the synthesis of some novel indeno[1,2-b]benzofuran derivatives by reaction of ninhydrin with cyclic 1,3-dicarbonyl compounds including cyclopentane-1,3-dione, cyclohexane-1,3-dione, dimedone, 4,4-dimethylcyclohexane-1,3-dione, meldrum's acid, barbituric acid, thiobarbituric acid, 1,3-dimethylbarbituric acid and indane-1,3-dione. We also used tetra-propylammonium bromide (TPAB) as an organocatalyst.

Palavras-chave : Cyclic 1,3-dicarbonyl compounds; ninhydrin; indeno[1,2-b]benzofurans; TPAB.
