molecular hybrids have been designed and a 1,3-dipolarcycloaddition strategy was devised to prepare the desired prototypes. A library of compounds with a wide range of diversity have been developed by employing β-carboline-containing dipolarophiles as well as dipoles. The current method represents a simple, efficient and easy-to-execute protocol towards the regioselective synthesis of β-carboline–isoxazole

Novel β-carboline–quinazolinone hybrids are able to inhibit Leishmania donovani TR (LdTR). Molecular docking studies to investigate possible binding sites were performed.
An efficient metal-free approach has been devised for the synthesis of novel β-carboline C-1 tethered 2,3-dihydropyrroles and pyrroles via one-pot assembly involving 1-formyl β-carbolines, aryl methyl ketones, and isonitriles. The reaction advances through the formation of β-carboline linked enones followed by [3+2] cycloaddition with isonitriles. This methodology features an operationally simple procedure
Substituted 1-formyl-9H-β-carbolines are demonstrated to be viable precursors for the synthesis of a library of new β-carboline-based polycyclic systems via1,3-dipolarcycloaddition strategy.
