Shirzaei, Farhad published the artcileBasic ionic liquid, 2-hydroxyethylammonium formate, catalyzed one-pot synthesis of novel 2-(phenylsulfonyl)-1H-benzo[a]pyrano[2,3-c]phenazin-3-amine derivatives, Formula: C9H10O3, the main research area is phenylsulfonyl benzopyranophenazinamine preparation green chem; hydroxynaphthalenedione benzenediamine arylaldehyde phenylsulfonyl acetonitrile condensation ionic liquid catalyst.
A new, one-pot, efficient, and four-component condensation of 2-hydroxynaphthalene-1,4-dione, benzene-1,2-diamine, arylaldehydes RCHO (R = Ph, 4-bromophenyl, 3,4,5-trimethoxyphenyl, etc.) and 2,3-dihydro-1H-indole-2,3-dione and (phenylsulfonyl)acetonitrile in the presence of a reusable basic ionic liquid, 2-hydroxyethylammonium formate, as catalyst for the synthesis of novel 2-(phenylsulfonyl)-1H-benzo[a]pyrano[2,3-c]phenazin-3-amine derivatives I and II under solvent-free conditions at 80°C was described. A simple reaction and work-up procedure for the synthesis of new un-known compounds I and II using a green and reusable ionic liquid as catalyst under solvent-free and thermal conditions was reported. The easy preparation of ionic liquid was superiority of the mentioned basic ionic liquid This protocol has various advantages such as short reaction times, excellent yields, no column chromatog., and green environmentally safe media.
