Elemental Sulfur-Promoted Benzoxazole/Benzothiazole Formation Using a C=C Double Bond as a One-Carbon Donator

An efficient method to assemble diverse benzoxazoles/benzothiazoles in good yields was developed via oxidative cyclization with 2-aminothiophenols or 2-iodoanilines as raw materials. In this protocol, elemental sulfur was used as the effective oxidant and C atoms on the C=C double bond were introduced as a one-carbon donator.

Elemental Sulfur-Promoted Oxidative Rearranging Coupling between o-Aminophenols and Ketones: A Synthesis of 2-Alkyl benzoxazoles under Mild Conditions

In the presence of N-methylpiperidine, elemental sulfur was found to act as excellent oxidant in promoting oxidative rearranging coupling between o-aminophenols and ketones. A wide range of 2-alkylbenzoxazoles was obtained under mild conditions.

Elemental sulfur mediated synthesis of benzoxazoles, benzothiazoles and quinoxalines: Via decarboxylative coupling of 2-hydroxy/mercapto/amino-anilines with cinnamic acids

An easy and practical method has been developed for the synthesis of 2-benzylbenzoxazoles and 2-benzylbenzothiazoles using sulfur mediated decarboxylative coupling of cinnamic acids with 2-hydroxyanilines and 2-mercaptoanilines respectively under metal- and solvent-free conditions. However, the reaction of 2-aminoanilines with cinnamic acids leads to the formation of 2-arylquinoxalines under the same set of reaction conditions. The transformation is versatile and compatible with a number of functional groups.

Palladium-catalyzed selective C-H benzylation towards functionalized azoles with a quaternary carbon center

The direct C-H benzylation of azoles with benzyl chlorides proceeds efficiently, via sequential cleavage of one sp2 C-H bond and two sp3 C-H bonds in the presence of a palladium catalyst, to generate a wide range of tribenzylated azoles with a quaternary carbon center efficiently. The same catalyst could also promote the mono- and di-benzylation reactions through fine turning of the base and reaction conditions. Copyright

An efficient synthesis of 2-substituted benzoxazoles via RuCl 3·3H2O catalyzed tandem reactions in ionic liquid

An efficient synthesis of 2-substituted benzoxazoles through RuCl 3·3H2O catalyzed, air oxidized tandem reactions of 2-aminophenols and aldehydes in [bmim]BF4 was developed. This synthetic strategy has such advantages as mild reaction conditions, cost-free oxidant, readily available starting materials, and recyclable catalyst and solvent. As an application, it was successfully used in the synthesis of the unreported 5-(benzoxazol-2-yl)-2′-deoxyuridines with potential biological activities. A novel and efficient synthesis of 2-substituted benzoxazoles through RuCl3 catalyzed, air oxidized tandem reactions of 2-aminophenols and aldehydes in [bmim]BF4 was developed.

Palladium-catalyzed direct benzylation of azoles with benzyl carbonates

"Chemical Equation Presented" The direct aromatic sp2 C-H benzylation of azole compounds with benzyl carbonates proceeds efficiently in the presence of a Pd2(dba)3/dppp catalyst system and KaOAc as a base to afford the corresponding diarylmethanes in good yields. In addition, the same palladium catalyst enables the direct benzylic sp3 C-H benzylation with the second benzyl carbonates without employing any external base.
