One-step Conversion of Esters to Acyl Azides Using Diethylaluminum Azide

Diethylaluminum azide, prepared from either sodium azide and diethylaluminum chloride or hydrazoic acid and triethylaluminum, reacts with esters to yield acyl azides in one step.

FeCl36H2O-Catalyzed acceleration of the acylation of sodium azide with n-acylbenzotriazoles

Catalyzed by ferric chloride hexahydrate (FeCl36H2O), the acylation of sodium azide with N-acylbenzotriazoles was greatly accelerated in a mixed solvent of acetone and water. Thus, good to excellent yields of a variety of acyl azides were obtained at room temperature in a short time. Furthermore, because of the complete conversion of N-acylbenzotriazoles and the easy removal of the by-product, purification by column chromatography was no longer required, which made the protocol suitable for large-scale preparation.

Visible Light-Induced Regioselective Cycloaddition of Benzoyl Azides and Alkenes to Yield Oxazolines

Visible light catalysis allows the regioselective synthesis of oxazolines in high yields. The mild photosensitized manifold leverages the intermolecular formation of oxazolines with a wide functional group tolerance on both benzoyl azides and alkenes part

Palladium-Catalyzed One-Pot Synthesis of N -Sulfonyl, N -Phosphoryl, and N -Acyl Guanidines

An efficient palladium-catalyzed cascade reaction of azides with isonitrile and amines is presented; it offers an alternative facile approach toward N -sulfonyl-, N -phosphoryl-, and N -acyl-functionalized guanidines in excellent yield. These series of substituted guanidines exhibit potential biological and pharmacological activities. In addition, the less reactive intermediate benzoyl carbodiimide could be isolated by silica gel column flash chromatography in moderate yield.
