Intramolecular coupling of vinyl ether and Olefins or acetylenes with Ti(II) reagent. Regio- and stereo-selective vinyltitanation of carbon-carbon multiple bonds
Treatment of m-alkenyl (or m-alkynyl) vinyl ethers (m=3,4) with a Ti(II) reagent generated most likely bicyclic oxatitanacycles, which eliminate the alkoxide tether to effect the selective vinyltitanation of the alkene or alkyne moiety to give m-vinyl-1-alkanols or m-vinyl-m-alken-1-ols.
