Intramolecular Hydrosilylation and Silicon-Assisted Cross-Coupling: An Efficient Route to Trisubstituted Homoallylic Alcohols
摘要:
[GRAPHICS]Alkylidenesilacyclopentanes (formed by intramolecular hydrosilylation of homopropargyl alcohols) are efficiently coupled with aryl or alkenyl halides in the presence of tetrabutylammonium fluoride and a palladium(0) catalyst. Yields of cross-coupling were generally high, and the reaction is compatible with a wide range of functional groups. The overall transformation achieves the conversion of homopropargyl alcohols to trisubstituted homoallylic alcohols in a highly stereoselective fashion.
