- Synthesis of 2,3-dihydro-1H-2-benzazepin-1-ones and 3H-2-benzoxepin-1-ones by isocyanide-based multicomponent reaction/Wittig sequence starting from phosphonium salt precursors
-
A one-pot synthesis of multisubstituted 2,3-dihydro-1H-2-benzazepin-1-ones and 3H-2-benzoxepin-1-ones by an I-MCR/Wittig sequence was developed. The reaction of phosphonium salt 3, arylglyoxals 4, amine 5 (or without), and isocyanide 6 produced the 2,3-di

- Performance comparison of two cascade reaction models in fluorescence off-on detection of hydrogen sulfide
-
Comparative studies on the performances of two cascade reaction based fluorescent H2S probes are reported. These probes were also designed to address the solubility issues of existing probes. The Reso-N3 probe favors the H2S mediated azide-to-amine reduction followed by a cyclization to release the resorufin fluorophore. Reso-Br undergoes a bromide-to-thiol nucleophilic substitution followed by a similar cyclization releasing the same fluorophore. Reso-N3 exhibited lower background fluorescence and better H2S sensing behavior in water compared to Reso-Br. Reso-Br underwent hydrolysis in aqueous buffer conditions (pH = 7.4) while, Reso-N3 was quite stable. Reso-N3 displayed high selectivity and sensitivity towards H2S. Live cell imaging of the species by the probe was also established. This journal is

The direct synthesis of new hemilabile ligands from the economical, readily available lactone phthalide is described. Pd-complexes of one such ligand were found highly effective in general Suzuki-Miyaura cross-coupling reactions, including deactivated and hindered aryl chlorides. The Royal Society of Chemistry 2013.

- SAR and lead optimization of an HIV-1 Vif-APOBEC3G axis inhibitor
-
We describe structure-activity relationship and optimization studies of RN-18, an HIV-1 Vif-APOBEC3G axis inhibitor. Targeted modifications of RN-18 ring C, ring B, ring A, bridge A-B, and bridge B-C were performed to identify the crucial structural features, which generated new inhibitors with similar (4g and 4i) and improved (5, 8b, and 11) activities. Two potent water-soluble RN-18 analogues, 17 and 19, are also disclosed, and we describe the results of pharmacological studies with compound 19. The findings described here will be useful in the development of more potent Vif inhibitors and in the design of probes to identify the target protein of RN-18 and its analogues.

A variety of 2-(1-bromoalkyl) benzoic acids 4 undergo intramolecular nucleophilic substitution reaction when treated with a CsF-Celite as solid base in acetonitrile under reflux condition to give the corresponding cyclized phthalides in moderate to very good yield. These 2-(1-bromoalkyl) benzoic acids 4 are formed by the α-bromination of 2-alkylbenzoic acids 3 using N-bromosuccinimide and a catalytic amount of α,α′ -azoisobutyronitrile in carbon tetrachloride under reflux.
