1.Ligand used in the Ru- and Cu-catalyzed enantios elective propargylic alkylation of propargylic alcohols with ß-ketoesters [1] and ß-keto phosphonates.
2.Used in the synthesis of highly substituted chiral v-lactams via catalytic asymmetric formal 3+2
cycloaddition of 2-isocyanatomalonate esters and uns aturated imines .
3.Ligand for the Cu-catalyzed 3+2- and 3+3-cycloadditions of(Z)-v-ethyI enoldiazoacetate with diaziridine.
