A facile, one-pot three-component protocol for the synthesis of 2-amino-4H-chromene derivatives has been demonstrated using Bael Fruit Extract (BFE) as a natural catalyst in a green reaction medium. This method offers a mild, efficient and highly economical protocol since the reaction proceeds in natural BFE-catalyst at room temperature under aerobic conditions with a very short reaction time (30 min) under ligand/external catalyst/external promoter-free conditions and, therefore, it is a green and environmentally sound alternative to the existing protocols. The catalyst was obtained by thermal treatment followed by water extraction of the rind of Aegle marmelos (bael) fruit. It was also found to be clean, high-yielding and has the capacity for large scale synthesis. © 2017 The Royal Society of Chemistry.

The synthesis of a series of 3-pyridyl-6-aryl-s-triazolo (3. 4-b) (1, 3. 4) - thiadiazoles are described, synthesis of 3-pyndyl-6-aryl-s-triazolo (3. 4-b) (1, 3, 4) - thiadiazoles (3a-m) have been achieved by the condensation of potassium dithiocarbazinate (1) with hydrazine hydrate and water. was under reflux 8 hours to yield 4-amino-3-pyridyl-5-mercapto-s-triazole (2). followed bv treatment with aromatic acid The compounds (3a-m) were characterized by spectral and elemental analyses. All thirteen compounds have been assayed for their fungicidal activity against P. oryzae. B. cinerea, A. nigar, C. albicans and T. rubrum. Compounds containing aryl substituents at position six and the 1. 2, 4-triazole moiety at position one or two showed reasonable fungicidal activity.

Syntheses of a series of 4-amino-3,5-dialkyl-1,2,4-triazoles are described. In present work, iminoester hydrochlorides (1) was treated with acyl hydrazines to obtain acylhydrazones (2). The compound acylhydrazones (2) converted to the 4-amino-3,5-dialkyl-1,2,4-triazoles (3) in good yields by treatment with hydrazine hydrate. The newly compounds were characterized by spectral and elemental analyses. Some compounds were screened for their antibacterial activity against S. aureus, E. coli, B. subtilis and P. aeruginosa. All compounds carring 1,2,4-triazole moiety showed significant antimicrobial activity.

Syntheses of a series of 3-alkyl(aryl)-4-tetrachlorophthalimido-4,5-dihydro-1H-1,2,4-triazol-5-ones and 3-alkyl(aryl)-4-(1,8-naphthalimido-4,5-dihydro)-1H-1,2,4-triazol-5-ones are described. The newly compounds were characterized by spectral and elemental analyses. Some compounds were screened for their antiinflammatory activity. All the compounds carring 1,2,4-triazole moiety showed significant antiinflammatory activity.

Various ether and ester derivatives of 1-naphthol were synthesized using polymer-supported reactions and evaluated for their antimicrobial activities, namely, antibacterial potency. In general, the derivatization of 1-naphthol was found to be more advantageous against the bacteria than parent molecule 1-naphthol.
