Abstract: The preparation of several disulfonamides 3 and 4 derived from camphor are described, as well as their use in the titanium tetraisopropoxide-promoted enantioselective addition of diethylzinc to benzaldehyde, the enantiomeric ratio being up to 82.0:18.0.

Keywords: Titanium, dialkylzinc, enantioselective addition.
