  The First Example of the 1-Chalcogene-Substituted Formylolefination of the Ketones and Aldehydes Using 1-Lithio-2-ethoxyvinyl Chalcogenides

  摘要：

  The alpha-chalcogene-substituted formylolefinations of ketones and aldehydes proceeded using 1-lithio-2-ethoxyvinyl chalcogenides/PPSE or TMSOTf produce the alpha-chalcogenoformylolefinated products 4a-1 in high yields. Tandem-formylolefination provided the (2Z,4Z)-2,4-bis(chalcogeno)pent-2,4-dienals 5d,h,i and (2Z,4Z,6Z)-2,4,6-tris(phenylthio)hept-2, derivatives 7d and 8d, respectively.

  preparation of a diverse array of multisubstituted α-selenoenals and -enones from readily accessible propargylic alcohols and diselenides. The transformation proceeds via the Selectfluor-promoted selenirenium pathway, which enables selenenylation/rearrangement of a variety of propargylic alcohols. Gram-scale experiments showed the potential of this synergistic protocol for practical application.

  我们描述了一种温和且广泛适用的方案，用于从易于获得的炔丙醇和二硒化物制备多种多样的多取代的α-硒烯醛和-烯酮阵列。转化通过Selectfluor促进的硒鎓途径进行，该途径可实现各种炔丙醇的硒烯基化/重排。克级实验显示了这种协同协议在实际应用中的潜力。
