The synthesis of xanthenes has been improved by condensing -naphthol with aldehydes in the presence of an acid catalyst such as sulfamic acid [17], Amberlyst-15 [18], AcOH-H 2 SO 4 [19], p-TSA [20] and silica sulfuric acid [21]. Some of these methods suffer from severe drawbacks, including use of large amounts of expensive reagents and catalysts, low yield, use of toxic solvents and catalysts, long reaction times, special apparatus, and tedious workup procedures, [17] B.

Sulfonated cellulose and starch: New biodegradable and renewable solid acid catalysts for efficient synthesis of quinolines Ahmad Shaabani, Abbas Rahmati, and Zahra Badri, Cat. Commun., 2008, 9, Catalyst preparation: To a magnetically stirred mixture of cellulose (5.00 g) or starch (5.00 g) in CHCl 3 (20 ml), chlorosulfonic acid (1.00 g, 9 mmol) was added dropwise at 0 o C during 2 h. After addition was complete, the mixture was stirred for 2 h until HCl was removed from reaction vessel. Then, the mixture was filtered and washed with methanol (30 ml) and dried at room temperature to obtain cellulose sulfuric acid as white powder (5.22 g) or starch sulfuric acid as cream powder (5.06 g). Sulfur content was analyzed by conventional elemental analysis, was 0.55 and 0.12 mmol/g for cellulose sulfuric acid and starch sulfuric acid, respectively. The number of H + site of cellulose-SO 3 H and starch-SO 3 H was determined by acid–base titration was 0.50 and 0.10 meq/g, respectively. This value corresponds to about 90% and 83% of the sulfur content, indicating that most of the sulfur species on both of the samples are in the form of the sulfonic acid groups.

Javad Safari, Sayed Hossein Banitaba, Shiva D. Khalili, Journal of Molecular Catalysis A: Chemical, 2011, 335, 46–50 Cellulose sulfuric acid catalyzed multicomponent reaction for efficient synthesis of 1,4-dihydropyridines via unsymmetrical Hantzsch reaction in aqueous media 1,4-Dihydropyridines (1,4-DHPs) are important class of compounds in the field of drugs and pharmaceuticals [9]. The DHP moiety is common to numerous bioactive compounds which include various antihypertensive, vasodilator, antimutagenic, antitumor and antidiabetic agents [10–13]. 1,4-DHPs are generally synthesised by classical Hantzsch method, which involves cyclocondensation of an aldehyde, -ketoesters and ammonia either in acetic acid or in refluxing ethanol for long reaction times which typically leads to low yields [14–16].

The mixture was stirred for 30 min at 0 C and then heated to 40–50 C for 2 h. SOCl2 was removed via reduced pressure distillation. The crude material, followed by repeated recrystallization in ligroin, then dried under vacuum, gave the desired product (56 g, 98%), colourless, mp 65–66 o C Chemical modification of CA with CSC CSC solution (3 g, 11 mmol of CSC dissolved in 20mL acetone) was dripped to CA solution (5 g, 19 mmol of CA dissolved in 50mL dry acetone) in ice-bath accompanied by stirring and nitrogen protection. The CA solution containing 4-dimethylaminopyridine (0.025 g) as the catalyst and Et 3 N (1.5 mL, 11 mmol) was stirred at 0–5 C for 3 h, and then at room temperature for 2 days. Eventually, it was poured into MeOH. The white precipitate was collected and purified by repeatedly washing. Further purification of the product was performed by Soxhlet extraction with MeOH for the first 2 h, after which the solvent was changed for fresh one and the extraction was conducted for the additional 24 h. Then the end product was dried under vacuum at 85 C and stored in desiccators. Yield: 7.29 g, 99.2%.
