B. Kishore* and G. Brahmeshwari

ABSTRACT

Multi component reactions (MCRs), because of their productivity, simple procedures, time-saving manner, convergence and facile execution, are one of the best tools in organic synthesis. MCRs, particularly those performed in environmentally friendly media, have been increasingly useful tools for the synthesis of biologically important compounds because of their environmentally friendly, atom economy, and green characteristics.

Keywords: N, N N', N'- tetrabromobenzene-1,3- disulfonamide (TBBDA), one-pot pseudo four component synthesis, benzimidazolyl chromeno [2,3-d] pyrimidines, antimicrobial activity.
