We describe here an extremely simple procedure for the enantioselective addition of allyltributyltin to aldehydes in the presence of a binaphthol-titanium complex. In toluene or pentane, the reaction can be performed at room temperature in the absence of molecular sieves without a decrease in the enantioselectivity. Enantiomeric excesses of up to 99% can be obtained in the most favourable cases. (C) 2000 Elsevier Science Ltd. All rights reserved.
