1,2-Ethylene-3,3-bis(4′,4″-dimethoxytrityl chloride), (E-DMT) was developed as a novel, bifunctional protecting reagent. This new compound was found to have a potential as a multipurpose acid-labile protecting reagent which can afford a 5′,5′-tritylthymidine dimer and a unique 5′,3′-cyclic protected thymidine derivative in modest to good yields.

Synthetic receptors and a series of new receptors were designed and synthesized for theobromine, a xanthine alkaloid used as a diuretic. The binding results of the theobromine and caffeine were also studied using NMR and UV methods. It was observed that the synthesis of the receptor H6 is achieved by Co(PPh3)3Cl-mediated homocoupling of 3-(ethoxycarbonyl)benzyl bromide 12 under mild conditions.

Artificial receptors (1-5) have been designed and synthesized from simple precursors. The chain length selectivity studies of dicarboxylic acids within the cavities of new fluorescent Troger's base molecular frameworks (1- 3) have been carried out with a critical examination of their role of rigidity as well as flexibility in selective binding in comparison to receptor 5. The chiral resolution of the racemic Troger's base receptors (1 and 2) by chiral recognition with (+)- camphoric acid using hydrogen-bonding interactions has been studied.
Aromatic aldehydes from benzylbromides via Cobalt(I) mediated benzyl radicals in the presence of aerial oxygen: A mild oxidation reaction in neutral condition

Co(PPh3)3Cl has been shown to be a novel mediator for the conversion of benzylic bromides to aromatic aldehydes under mild conditions in the presence of acnal oxygen probably via benzylic radicals. In the absence of oxygen, the carbon-carbon coupling reactions have been utilised to attend a series of functionalised benzylic dimers.
