Binaphthol as a chiral auxilliary: Diastereoselective alkylation of binaphthyl esters of α,β-unsaturated carboxylic acids

Article abstract of DOI:10.1016/0040-4039(91)80498-U

Binaphthyl esters of α,β-unsaturated carboxylic acids are alkylated at the α-position concomitant with the migration of the double bond to the β,γ-position with high diastereoselectivity.
