titanium tetraisopropoxide, BINOL, 2-propanol additive, and tetraallylstannane as allylating agent. A variety of ketone substrates, including acetophenone derivatives and alpha,beta-unsaturated cyclic enones, reacted to form tertiary homoallylic alcohols in good yields (67-99%) and with high levels of enantioselectivity (generally >80%). A novel one-pot enantioselective allylation/diastereoselective

In/InCl3-mediated addition of allyl iodide to alpha,beta-unsaturated carbonyl compounds gave moderate to high yields of 1,2-addition products. The reactions covered acylic and cyclic alpha,beta-unsaturated carbonyl compounds. Indium trichloride was effective for these Barbier-type allylation reactions.
