A simple and clean procedure for the synthesis of polyhydroacridine and quinoline derivatives: reaction of Schiff base with 1,3-dicarbonyl compounds in aqueous medium
A clean and simple synthesis of benzo[c]acridine, benzo[a]acridine, pyrido[2,3-c]acridine and benzo[f]quinoline derivatives was accomplished in good to excellent yields via the reaction of Schiff base with 1,3-dicarbonyl compounds in aqueousmediumcatalyzed by TEBA. The structures were characterized by 1H NMR, IR and elemental analysis, and confirmed by X-ray diffraction study.

The first example of glucose-containing Brønsted acid synthesis and catalysis: efficient synthesis of tetrahydrobenzo[α]xanthens and tetrahydrobenzo[α]acridines in water
Glucose sulfonic acid (GSA) was synthesized for the first time and used as an efficient catalyst for the preparation of tetrahydrobenzo[alpha]xanthens and tetrahydrobenzo[alpha]acridines via the reaction of aromatic aldehydes, 2-naphthol (or beta-naphthylamine), and dimedone in water. Up to four new bonds and one new ring were formed in one-pot with water as the only by-product in these two reactions. The work opens up a new and efficient synthesis and application of sugar-containing Bronsted acid. (C) 2013 Elsevier Ltd. All rights reserved.
A clean synthesis of polyhydroacridine and indenoquinoline derivatives catalyzed by triethylbenzylammonium chloride in aqueous media
An efficient and convenient synthesis of benzo[a]acridines and indeno[1,2-b]benzo[f]quinolines was achieved in high yields by the reaction of N-arylidenenaphthalen-2-amine with 1,3-dicarbonyl compounds catalyzed with triethylbenzylammmonium chloride (TEBAC) in aqueousmedia. The structures were established by spectroscopic data and further confirmed by X-ray analysis. This method provides several advantages
