Intramolecular Vinylsilane−Oxocarbenium Condensations: Concise Assembly of Cis-Bicyclic Ether Arrays
摘要:
Lewis acid-mediated intramolecular attack of vinylsilanes at tethered oxonium precursors 1 results in a rapid assembly of the cis-fused bicyclic ether species 3, with complete regio- and stereospecific control, and in some cases near-quantitative yield. Continued investigation suggests a general approach to a variety of such ether frameworks.
