• Gold-Catalyzed Regioselective Hydration of Homopropargyl Alcohols Followed by Diastereoselective Reduction: An Easy Access to cis 2,5-Disubstituted Tetrahydrofurans

  A gold (III)-catalyzed hydration of homopropargyl alcohols led to the corresponding γ-hydroxy ketones, which were directly reduced by Ph3SiH in the presence of a Lewis acid, to afford the expected 2,5-disubstituted tetrahydrofurans as a diastereomeric mixture. NMR analysis of the compounds so obtained allowed us to confirm that the cis isomers were the major isomers that can be used for the preparation of new products.

  一种金(III)催化的同源丙炔醇水合反应生成了相应的γ-羟基酮，这些酮在路易斯酸的存在下被Ph3SiH直接还原，得到了预期的2,5-二取代四氢呋喃作为一种diastereomer混合物。对所获得化合物的NMR分析使我们确认，顺式异构体是主要异构体，可以用于新产品的制备。
