Indium-mediated organometallic reactions in aqueous media. Stereoselectivity in the crotylation of sulfonimines bearing a proximal chelating group.
Reaction of sulfonimines having proximal chelating groups with crotyl bromide and indium in aqueous media gave alpha-crotylation products stereoselectively with syn-selectivity.
