  Formation of Angularly-Fused Triquinanes by Successive Use of the Pauson-Khand Reaction and Radical Closure

  摘要：

  Angularly-fused triquinanes (see Table 1) are accessible by sequential use of the Pauson-Khand reaction and radical cyclization. The Pauson-Khand step works in the presence of homolyzable bonds, such as C-Br and C-SePh. The method seems best suited to the preparation of triquinanes containing heteroatoms, as the starting materials are then easily made. In one case the radical closure step (15 --> 16 and 17) generated two five-membered rings fused in a trans manner; this stereochemistry was confirmed by X-ray analysis of the crystalline product.

  Au-catalyzed intramolecular hydroalkoxylation of gem-difluorinated alkynols

  摘要：

  The intramolecular hydroalkoxylation of gem-difluorinated alkynols was found possible under Au catalysis, allowing for the preparation of a series of fluorinated heterocycles. The nature of the solvent was found to be especially critical in the cyclization of gem-difluorohomopropargylic alcohols as it dictated whether the resulting 2,3-dihydrofuran underwent subsequent aromatization to the corresponding furan or not.
