 Formally, this process provides anti-carboalumination products that can be quenched with electrophiles.A limitation of this methodology is that the directing group must be sufficiently close to the carbon-carbon π-bond to form a thermodynamically favorable ring or else mixtures of geometric isomers will form.The carboalumination of alkenes to form substituted alkanes can be rendered enantioselective if prochiral alkenes are used.
