Coupling of AlkynylTMS Derivatives with Vinylic Iodides. An Efficient Route to 1,3-Enynes and Dienes
摘要:
[GRAPHICS]CuCl-promoted coupling of alkynylTMS derivatives with vinyl iodides leads to 1,3-enynes in high yield. Enynes prepared! from homopropargylic alcohols undergo intramolecular hydrosilylation and subsequent silyl cleavage with TBAF to afford 1,3-dienes.
