Transition metal compounds with cyclometalating ligands have attracting widely spread and increasing interest due to their efficient luminescent properties and
Cyclization is an inevitable side reaction occurring in any step-growth polymerization,but optimizing the yield of a single cyclic structure is usually one of t
We recently developed an organocatalytic asymmetric direct vinylogous Michael addition of an α,β -unsaturated γ-butyrolactam (Nu) with chalcone (EI) catalyze
