B(C6F5)3-Promoted Tandem Silylation and Intramolecular Hydrosilylation: Diastereoselective Synthesis of Oxasilinanes and Oxasilepanes
摘要:
B(C6F5)(3) promotes regio- and stereoselective cyclizations of unsaturated alkoxysilanes to generate oxasilinanes and oxasilepanes. The same products are available directly from alkenols via tandem silylation and hydrosilylation.

5-Hydroxylalkenes react with rhenium(VII) oxide in the presence of another oxidant, H5IO6, to provide substituted tetrahydrofurans. The yield and stereoselectivity are comparable to stoichiometric results.
