A multi component based synthesis involving palladium catalyzed C-C bond forming reaction has been developed as a new strategy to access systematically modified functionalized 2-aminochromenes. This MCR involves the use of bromobenzaldehyde as a key component and is highlighted by generating a new compound library. Many of these compounds showed Mycobacterium tuberculosis H37Rv chorismate mutase inhibiting properties in vitro representing the lead example of chorismate mutase inhibition by heteroarene based compounds.

We report the design, synthesis and evaluation of a series of 4-biaryl substituted 2-amino benzo[h]chromene derivatives as potential cytotoxic agents. Methods: The one-pot synthesis of this class of compounds was carried out under ultrasound irradiation using an MCR involving Pd/C-catalyzed Suzuki-Miyaura coupling as a key step. Result and Conclusion: Several of these compounds showed promising cytotoxicities
