spiroacenaphthylene, benzo[α]cyclooctenes, etc. Therefore, development of an efficient method for a MCR which encompass vinylogous Michael addition as vital reaction is of current interest. Methods: We explored catalytic efficiency of DABCO in the multi-component reaction of cyclic ketone, aldehyde and two moles of malononitrile for the synthesis of functionalized condensed bicyclic compounds viz tetrahydroindenes

strategies for the synthesis of the title compounds is that of multicomponent reactions (MCRs). In MCRs three or more reactants form products such that all or most of the initial atoms are present in the final product. This has clear benefits in terms of cost, efficiency and environmental stewardship. There are some literature methods for the synthesis of ortho-aminocarbonitrile derivatives, and these include
