  FeCl₃ · 6H₂O-Catalyzed Acceleration of the Acylation of Sodium Azide withN-Acylbenzotriazoles

  摘要：

  [image omitted] Catalyzed by ferric chloride hexahydrate (FeCl3 center dot 6H2O), 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.

  Efficient Microwave Access to Polysubstituted Amidines from Imidoylbenzotriazoles

  摘要：

  Microwave reactions of primary and secondary amines with imidoylbenzotriazoles 6a-w gave diversely substituted amidines 7a-Aa in 76-94% yields. Convenient preparations of a variety of amides 5a-Ab (87-96%) and imidoylbenzotriazoles 6a-w (56-95%) have also been developed using microwave irradiation under mild conditions and short reaction times. These results demonstrate further the advantages of microwave synthesis and introduce a new application of imidoylbenzotriazoles in the preparation of polysubstituted amidines.

  Abstract Catalyzed by samarium triiodide (SmI3), substitution of acyl with N‐acylbenzotriazoles for acetyl in acetoacetic esters and acetylacetone proceeds smoothly under neutral conditions in open air, affording the corresponding β‐keto esters and β‐diketones in good yields.

  日期：2003.6

  N-Acylbenzotriazoles, when treated with samarium diiodide in THF, undergo self-coupling reaction to afford 1,2-diketones in good to excellent yields; while when treated with samarium diiodide in CH3CN, they undergo ring-opening reaction to afford 1-acylamido-2-alkyl (or aryl) benzimidazoles in reasonable to good yields. A plausible mechanism was suggested.

  N-酰基苯并三唑在THF中用二碘化sa处理时，会发生自偶联反应，从而以良好或极好的收率得到1,2-二酮；当在CH 3 CN中用二碘化sa处理时，它们会发生开环反应，以合理至良好的收率获得1-酰氨基-2-烷基（或芳基）苯并咪唑。提出了一个合理的机制。

  Thioesters undergo chemoselective soft enolization and acylation with N-acylbenzotriazoles on treatment with MgBr2˙OEt2 and i-Pr2NEt to give β-keto thioesters. Prior enolate formation is not required and the reaction is conducted using untreated dichloromethane open to the air.

  N-Aryl and N-alkenyl carbamoyl benzotriazoles were prepared in good to excellent yields from acyl azides and benzotri-azole via Curtius rearrangement, while N-alkylcarbamoyl benzotriazoles were formed from N-alkanoyl benzotriazoles and sodium azide in one pot. The carbamoyl benzotriazoles can be used as a stable isocyanate alternative, as has been demonstrated by its reaction with amines to synthesize
