This account deals with an overview of the development of catalytic addition reactions of carbonyl compounds to alkynes catalyzed by a variety of indium salts. The new C-C bond formation reactions provide a powerful tool for α-functionalization of carbonyl compounds, including direct α-vinylation with acetylene, regioselective α-alkenylation, and α-ynenylation that can be applied to a modular synthesis of α-arylated β-keto esters.

Moreover, facile recycling and reusability, the <a>hallmark</a> of heterogeneous catalysts, were kept for the homogeneous CN photocatalyst via reversible precipitation using poor solvents. It opens new vista of CN in homogeneous catalysis and offers a successful example of polymeric catalysts in bridging gaps of homo/heterogeneous catalysis.

Bond Formation Reactions

C-N bond formation is a particularly important step in the generation of many biologically relevant heterocyclic molecules. Several methods have been reported for this purpose over the past few decades. Well-known named reactions like Ullmann-Goldberg coupling, Buchwald-Hartwig coupling and Chan-Lam coupling are associated with the C-N bond formation reactions. Several reviews covering this topic have already been published. However, no comprehensive review covering the synthesis of drugs/ lead compounds using the C-N bond formation reactions was reported. In this review, we cover many modern methods of the C-N bond formation reactions, with special emphasis on metal-free and green chemistry methods. We also report specific strategies adopted for the synthesis of drugs, which involve the C-N bond formation reactions. Examples include anti-cancer, antidepressant, anti-inflammatory, anti-atherosclerotic, anti-histaminic, antibiotics, antibacterial, anti-rheumatic, antiepileptic and anti-diabetic agents. Many recently developed lead compounds generated using the C-N bond formation reactions are also covered in this review. Examples include MAP kinase inhibitors, TRKs inhibitors, Polo-like Kinase inhibitors and MPS1 inhibitors.
