A novel sulfonated diamine monomer, 1,4-bis(4-aminophenoxy)-naphthyl-2,7-disulfonic acid (BAPNDS), was synthesized. A series of sulfonated polyimide copolymers were prepared from BAPNDS, 1,4,5,8-naphthalenetetracarboxylic dianhydride... more
Fructone (2-methyl-2-ethylacetoacetate-1, 3-dioxolane), a flavouring material, has been synthesized from ethyl acetoacetate and glycol using five water-soluble Brønsted acid ionic liquids as catalysts for the first time. The used Brønsted... more
An unusual oleanane triterpene (1) was isolated from aerial parts of Rhododendron campanulatum. The compound had shown prominent antibacterial and immunomodulatory activities. The structure of the compound was determined by spectroscopic... more
A simple and convenient procedure for reductive amination of aldehydes and ketones using N-methylpyrrolidine zinc borohydride (ZBHNMP) as a reducing agent is described. The reactions are carried out with 1 equiv of amine and 1 equiv of... more
Platinum containing compounds have shown antineoplastic potential, but their clinical applications have been limited by high toxicity. Ruthenium containing complexes have long been known to be well suited for biological applications, and... more
Oxidative cyclocondensation of o-aminobenzamide with various aldehydes in water using I2/KI as catalyst and oxidizing agent is carried out giving the corresponding quinazolin-4(3H)-ones 3a–n in good to excellent yields.
A combination of iodic or periodic acids and sodium nitrite in the presence of wet SiO2 was used as an effective nitrosating agent for the nitrosation of secondary amines to their corresponding nitroso derivatives under mild and... more

Silica supported perchloric acid (HClO4-SiO2) is found to be a recyclable heterogeneous catalyst for a rapid and efficient synthesis of various 14-aryl or alkyl-14-H-dibenzo[a,j]xanthenes with good to excellent yields under reflux and... more
The green reaction of isatoic anhydrides with α-amino acids in presence of the ionic liquid 1-butyl-3-methylimidazolium bromide afforded 1,4-benzodiazepine-2,5-diones in excellent yields in absence of a catalyst. The reaction workup is... more
The regiospecific oxidation of alkyl group of both sterically hindered and unhindered aromatic amine to corresponding carbonyl compounds was done in aq. medium by using DDQ. the optmized reaction protocol was found to be most simple,high... more
