摘要：
The R-1 substituents at C(2) of the haloallylic sulfones 1 play a pivotal role in controlling the diastereoselectivity of the indium-mediated addition reaction to benzalclehyde to produce the homoallylic alcohols 3. The R, Me group of 1 prefers the chair form in the In-coordinated six-membered cyclic transition state to give anti-3a, and the R-1 Ph group of 1 favors the twist boat form to give syn-3n, both in a high 13:1 selectivity.
