Abstract
A tunable reaction manifold of alkynyl sulfonium salts with binucleophilic N-aryl amidines in the absence of any transition metal catalyst is first reported. This methodology involves sequential addition/cyclization that is perfectly tuned by stepwise addition of K2CO3, affording a plethora of valuable 1,2,4- and 1,2,5-trisubstituted imidazoles in good yields with high regioselectivity. Importantly, trapping and isolation of the reactive intermediate unveiled the reaction mechanism of β-attack on the triple bond in this [3 + 2] cycloaddition reaction.

Abstract
Dimethyl sulfoxide (DMSO)-promoted catalyst-free oxidative C-N coupling and C-O coupling under oxidant-free conditions are outlined. This protocol is operationally simple and leads to various functionalized substituted imidazoles or oxazoles in good yields. To date, a very limited number of oxidation protocols have been established, where DMSO acts solely as a catalyst or an oxidant or both. In this report, DMSO is not only used as a C-N/C-O coupling agent but is also used as the oxidant required for these oxidative transformations. Hence, our demonstrated DMSO-promoted catalyst-free coupling transformation has the ability to lead to a new dimension in the field of oxidative coupling.

Abstract
INTRODUCTION A simple method for the preparation of 5-(trifluoroacetyl)imidazoles was elaborated. METHODS The reaction of trifluoromethyl(α-bromoalkenyl)ketones with benzimidamides was employed to afford the target heterocycles in good yields. RESULTS The assembly of imidazole core proceeds via aza-Michael adduct formation followed by intramolecular nucleophilic substitution and spontaneous aromatization as an oxidation sequence. CONCLUSION The yields of target imidazoles can be improved by the use of soft oxidizing agents.

Abstract
We have developed a direct method for the synthesis of polyring-fused imidazo[1,2-a]pyridines via a copper-catalyzed annulation of electrophilic benzannulated heterocycles with 2-aminopyridine and 2-aminoquinoline. From 3-nitroindoles and 2-aminopyridine, we could synthesize tetracenes, viz., indole-fused imidazo[1,2-a]pyridines, and by starting from 2-aminoquinoline, we could generate pentacenes, viz., indolo-imidazo[1,2-a]quinolines. In addition, we could also extend the methodology toward the synthesis of benzothieno-imidazo[1,2-a]pyridines starting from 3-nitrobenzothiophene. Furthermore, the basic photophysical properties of these synthesized heteroacenes were evaluated.

Abstract
An oxidative annulation of N-arylbenzimidamides with maleimides has been developed for the first time using a catalytic amount of the [Cp*RhCl2]2 complex for the synthesis of a diverse range of 1H-benzo[4,5]imidazo[2,1-a]pyrrolo[3,4-c]isoquinoline-1,3(2H)-dione derivatives. This method is versatile and atom-economical for producing polycyclic benzo[4,5]imidazo[2,1-a]pyrrolo[3,4-c] isoquinoline-1,3(2H)-dione scaffolds in a single step.

Abstract
Herein, we demonstrated the oxidative cross-dehydrogenative coupling between amidines and chalcones catalyzed by flavin and iodine. The riboflavin-iodine catalytic system played multiple roles in substrate- and O2-activation, enabling the facile and atom-economical synthesis of tetra-substituted imidazoles in good yields (60-87%). This metal-free reaction consumed only 1 equiv of molecular oxygen and generated 2 equiv of environmentally benign H2O as the only byproduct.

Abstract
A new and practical protocol for the synthesis of medicinally privileged azolo[1,3,5]triazines by simply heating under air has been presented. The in situ generated N-azolo amidines from commercially available aromatic aldehydes and 3-aminoazoles with ammonium iodide undergo the second diamination to accomplish the [3 + 1 + 1 + 1] heteroannulation reaction. This convenient process is appreciated by high efficiency, broad substrate scope, gram-scale synthesis, and operational simplicity under reagent-free conditions.
