Research Focus
Our research primarily centres on the following areas:
(i) Organocatalysis with phosphines: We routinely pursue metal-free chemistry with nucleophilic trivalent organophosphines. Some key contributions to this area include the development of asymmetric intramolecular Morita-Baylis-Hillman reaction and its variants, phosphine-promoted reductive and vinylogous aldol reactions, phosphine-catalyzed intramolecular hydroalkylation, and hydroacylation chemistry, etc.
(ii) Cascade transformation with sulphur slides: Sulfur ylides are traditionally employed to synthesize cyclopropanes, epoxides, and aziridines from the respective olefins, carbonyls, and imines. We articulated several one-pot cascade transformations employing sulfur ylides as reagents that provided facile access to unprecedented cyclopropanoids. We have manipulated the complexity of the molecular scaffolds by the rational design of the substrates.
