A novel and convenient transformation for the regiospecific synthesis of functionalized imidazo[1,2-a]pyridine aldehydes/ketones and 3-vinyl imidazo[1,2-a]pyridines has been developed via copper(I)- and palladium(II)-catalyzed cyclization. The one-pot reaction proceeds smoothly with commercially available catalysts and affords the products in moderate to good yields. It represents an efficient approach for the formation of C-N, C=O, and C=C bonds under mild conditions.

A convenient gold-catalyzed strategy for the synthesis of imidazo[1,2-a]pyridine derivatives has been developed via gold carbene complexes. This transformation opens a new synthetic route to a variety of 3-carbonyl-substituted imidazo[1,2-a]pyridines using air as oxidant affording the products in good yields.

An efficient and "green" protocol for the synthesis of 3-acylimidazo[1,2-a]pyridines through intramolecular oxidative α-amination of carbonyl compounds has been developed. The reaction proceeds smoothly utilizing I2 as a catalyst and H2O2 as an oxidant under neat condition with broad substrate scope. Several complex nitrogen-containing fused rings are conveniently constructed, which are not easy to access by traditional methods.

A transition-metal-free aerobic oxidative selective C-C bond-cleavage reaction in primary and secondary heteroaryl alcohols is reported. This reaction was highly efficient and tolerated various heteroaryl alcohols, generating a carboxylic acid derivative and a neutral heteroaromatic compound. Experimental studies combined with density functional theory calculations revealed the mechanism underlying the selective C-C bond cleavage. This strategy also provides an alternative simple approach to carboxylation reaction.

Abstract: A convenient and novel two-step one-pot method for the synthesis of 3-substituted imidazo[1,2-a]pyridines and 3-substituted imidazo[1,2-b]pyridazines was developed through the reaction of heterocyclic amines and N,?N-dimethylformamide dimethyl a

3-Acyl imidazo[l,2-a]pyridines with no substituent at position 2 were obtained in moderate to good yields in an improved version of the Tisler protocol for the synthesis of imidazo[l,2-x]azines. It was found that yields are significantly improved if the r
