Contrary to previous reports, it was found that hydrolysis of silyl enol ethers is superior to the desired condensation in lnCl3-catalyzed aldol reactions of silyl enol ethers with aldehydes in water. The reactions were found to proceed in certain amounts in the presence of a catalytic amount of a L
