  Direct Synthesis of Cyclic Ketals of Acetophenones by Palladium-Catalyzed Arylation of Hydroxyalkyl Vinyl Ethers

  摘要：

  Reaction of 2-hydroxyethyl vinyl ether, 4-hydroxybutyl vinyl ether, or di(ethylene glycol) vinyl ether with aryl triflates, aryl bromides, or iodobenzene in presence of a catalytical amount of palladium acetate and the bidentate ligand DPPP provides a direct entry to cyclic ketals of acetophenones. It is postulated that the reaction proceeds via an initial alpha-arylation of the vinyl ethers to give labile aryl vinyl ether intermediates, which undergo subsequent ketalization in presence of protons in the reaction media. The method merits attention due to the simplicity of the experimental procedure and the possibility of selective ketal formation in the presence of an additional carbonyl group.

  Indane-derived bis(oxazolines) were synthesized in two steps and 93% overall yield starting from commercially available substrates. This ligand is as effective as tert-butyl bis(oxazoline) in hetero Diels–Alder reaction both in solution and on polymer support.

  从市售底物开始，分两步合成了茚满衍生的双（恶唑啉），总产率为93％。该配体在溶液和聚合物载体上的杂Diels-Alder反应中与叔丁基双（恶唑啉）一样有效。

  with alkynyl trifluoroborates is described, proceeding through a cobalt hydride-mediated radical-polar crossover metal hydrogen-atom-transfer process. This method affords structurally diverse alkynyl-containing compounds in high yields under mild conditions and features a wide substrate scope, good functional group tolerance, and suitability for late-stage functionalization of relatively complex natural
