Abstract
TiCl4 mediated coupling of alkyl vinyl ketones with a-keto esters and aldeh ydes provides respectively 2-aryl-2-hydroxy-3-methylene-4-oxoalkanoates and (Z)-keto allyl chlorides in 1 h time at room temperature. Similar coupling of trifluoromethyl phenyl ketone with methyl vinyl ketone produces 1, 1, 1 trifluoro-2-hydroxy-2-phenyl-3-methylenepentan-4-one.
