Organocatalytic asymmetric Michael addition is considered among the most extensively studied, yet challenging stereoselective reactions due to the fact that the electrophilic prochiral carbon in Michael acceptor lies away from stereodirecting groups of the catalyst. Although there is a report on stereoselective organocatalysis in Michael addition employing monofunctional secondary amine, the use of monofunctional primary amine forthe said reaction is not reported till date. In fact, no monofunctional aminocatalyst is reported yet for the synthesis γ-nitro carbonyl compounds. Here we report our preliminary results on the enantioselective Michael addition of different ketones to nitro olefins catalysed by monofunctional primary amine (1) derived from d-fructose.

A series of coumarin-based trisubstituted methanes (TRSMs) having uracil scaffold was synthesised employing a green, chromatography-free, and a highly efficient sonochemical multicomponent reaction of diverse aldehydes with 1,3-dimethyl-6-aminouracil and 4-hydroxy-coumarin in the presence of acatalytic amount of DABCO at room temperature and tested their anthelmintic efficacy against helminth parasites,
