  Electrophilic 5-endo-trig cyclisations of 2-silyl-3-alkenols. A stereoselective route to polysubstituted tetrahydrofurans

  摘要：

  Electrophilic 5-endo-trig cyclisations of allylsilanes have been carried out leading to tri- and tetrasubstituted tetrahydrofurans with reasonable fields and excellent diastereoselectivities. A rationalization of both the regio- and the stereoselectivity has been proposed. A silicon group having a thienyl fragment attached to the silicon has also been devised was shown to be oxidized under both electrophilic and nucleophilic conditions. (C) 1997 Elsevier Science Ltd.

  A Stereospecific Access to Allylic Systems Using Rhodium(II)−Vinyl Carbenoid Insertion into Si−H, O−H, and N−H Bonds

  摘要：

  Rhodium-catalyzed decomposition of alpha-vinyldiazoesters in the presence of silanes, alcohols, ethers, amines, and thiols have been shown to produce the corresponding alpha-silyl, alpha-hydroxy, alpha-alkoxy, alpha-amino, and alpha-thioalkoxy esters in generally good yield with a complete retention of the stereochemistry of the double bond of the diazo precursor. An extension of the process in homochiral series has also been devised using either a chiral auxiliary attached to the ester function or achiral alpha-vinyldiazoesters and Doyle's chiral catalyst Rh-2(MEPY)(4). In the former approach, pantolactone as chiral auxiliary gave diastereoselectivities of up to 70%, while the second approach produced the desired allylsilane with ee as high as 72%. On the other hand, Rh-2(MEPY)(4)-catalyzed insertion into the O-H bond of water led to poor or no enantioselectivity in good agreement with recent literature reports.

  catalysed decomposition of vinyldiazocarbonyl compounds in the presence of organosilanes led stereospecifically to the corresponding allylsilanes in good yields. An asymmetric approach has also been considered as well as the extension of the methodology to the synthesis of other allylic systems.

  在有机硅烷的存在下，Rh 2（OAc）4催化的乙烯基重氮羰基化合物的分解立体定向地以良好的收率生成了相应的烯丙基硅烷。还考虑了不对称方法，以及将方法扩展到其他烯丙基系统的合成。
