  Oxidant-Controlled Stereoselectivity in the Pd-Catalyzed Allylic Oxidation of cis-Vinylsilanes

  摘要：

  The allylic oxidation of cis-vinylsilanes is reported. The reaction requires a low catalyst loading of Pd(OAc)(2) without the need for an external ligand. Interestingly, trans-vinylsilanes are unreactive, whereas allylic oxidations of cis-vinylsilanes proceed in good yields giving a single diastereo- and regioisomer of the branched allylic acetate trans-vinylsilane when benzoquinone is employed. The use of PhI(OAc)(2) as oxidant in place of benzoquinone provides the branched, cis-vinylsilane as the major product. Additionally, the first intramolecular allylic C-H etherifications of cis-vinylsilanes to give oxygen heterocycles are also described.

  (E)-Vinylsilanes were obtained with high selectivities by [Rh(COD)(2)]BF4/2PPh(3)-catalyzed hydrosilylation of 1-alkynes with triethylsilane. A wide range of 1-alkynes were used. The hydrosilylation of propargylic alcohols with triethylsilane gave (E)-gamma-silyl allylic alcohols 2h-r, a useful source of a chiral alcohol, with high selectivities in excellent yields. The reaction can be carried out without protecting the alcohol functionality. The resulting (E)-gamma-silyl allylic alcohols could be transformed into beta-silyl ketones. The isomerization was also catalyzed by [Rh(COD)(2)]BF4/2PPh(3). Furthermore, the tandem hydrosilylation-isomerization of secondary propargylic alcohols could be carried out in a one-pot procedure.
