- Dehydration-type Ti-Claisen Condensation (Carbonhomologation) of α-Heteroatom-substituted Acetates with Alkyl Formates: Utilization as (Z)-Stereodefined Cross-coupling Partners and Application to Concise Synthesis of Strobilurin A
-
TiCl4?Et3N or ?Bu3N reagent conducted a highly (Z)-stereoselective carbon homologation (dehydration type Ti-Claisen condensation) of alkyl α-heteroatom (halo and sulfonyloxy)-substituted acetates (XCH2CO2R) with alkyl formates (HCO2R) to afford various alkyl β-alkoxy-α-halo or sulfonyloxy-substituted acrylates (24 examples; 51%–91% yield). Stereoretentive Suzuki-Miyaura, Negishi, and Sonogashira cross-couplings using the obtained methyl β-methoxy-α-halo or sulfonyloxy-substituted acrylates proceeded smoothly to produce a variety of β-alkoxy-α-substituted acrylates in moderate to high yield (35 examples; 29%–99% yield). As a successful application, a 3-step straightforward synthesis of strobilurin A was performed utilizing the present reaction sequence (dehydration type Ti-Claisen condensation and Suzuki-Miyaura cross-coupling), wherein the geometry of the three consecutive olefins (2E,3Z,5E) was completely maintained. (Figure presented.).

- Method for preparing azoxystrobin on basis of Suzuki reaction
-
The invention relates to a method for preparing azoxystrobin on basis of a Suzuki reaction. The method comprises the following steps: dissolving a mixture composed of methyl (E)-2-[2-(6-chloropyrimidinyl-4-yloxo)phenyl]-3-methoxy acrylate, cesium carbonate and 2-cyanophenol according to a molar ratio of 1:2:2 in a solvent, stirring at 85DEG C under the protection of N2 for 7h, and separating and purifying the obtained mixture to prepare azoxystrobin. The novel green synthesis method provided by the invention has the advantages of low cost, high yield, simple process, and suitableness for mass production.
