Diastereoselective additions of alkyl, akenyl, aryl and allyl cuprates to unsaturated chiral imides

Some diastereoselective conjugate additions of cuprates to chiral unsaturated imides bearing an imidazolidinyl group (from ephedrine and urea) show an impressive stereoselectivity. The chiral (internal auxiliary dependent) group is easily broken and recyc
