A novel and efficient protocol for the synthesis of chiral tetrahydroquinoline derivatives with excellent enantioselectivities and high yields has been developed through one-pot cascade biomimetic reduction. The detailed reaction pathway includes the acid-catalyzed and ruthenium-catalyzed formation of aromatic quinoline intermediates and biomimetic asymmetric reduction.

Acrylamides are fundamental Michael acceptors which have been used profoundly in synthetic, medicinal and polymer chemistry. However, due to their lower reactivity they have been least used in Morita-Baylis-Hillman (MBH) reaction and have been out of its vinylogus version Rauhut Currier (RC) reaction. Herein, use of acrylamide in RC reaction is being presented. Intramolecular RC reaction followed by [1,3]-H shift led to the synthesis of quinolone moiety. DABCO catalyzed IRC reaction of acrylamide at 80 °C in presence of water, was found to work on a number of precursors. En route chemo selective, gram scale method for ambiphilic, versatile precursor 2-amino chalcone is also reported. Chemoselective and economical conversion of 2-nitro chalcone to 2-aryl quinoline has also been developed.

A new cross-cycloaddition reaction between a wide range of isocyanides and 2-isocyanochalcones (or analogues) was developed for the expeditious synthesis of pyrrolo[3,4-b]indoles under thermal conditions. On the basis of the experimental results and DFT c
