Design of new chemical approaches that enable increasingly rapid access to structural complexity from simple starting materials under eco-benign conditions remains challenging and very important paradigm for the chemical sciences. In this perception, a transition-metal catalyzed C-X (X = carbon or heteroatom) bond forming reactions via borrowing hydrogen strategy (a redox process) is considered to be the most promising atom-economic and eco-benign methods and received much attention. The primary objective of the proposal is to the synthesis of base-metal based complexes and to develop complete atom-economical and eco-benign synthetic methodology for the construction of important heterocyclic compounds such as dihydropyrrole derivatives via redox cascade strategy.
