Technical Notes:
1.Ligand used in the Ru- and Cu-catalyzed enantios elective propargylic alkylation of propargylic alcohols with ?-ketoesters[1]and ?-keto phosphonates.
2.Used in the synthesis of highly substituted chiral v-lactams via catalytic asymmetric formal3+2
cycloaddition of 2-isocyanatomalonate esters and uns aturated imines .
3.Ligand for the Cu-catalyzed3+2- and3+3-cycloadditions of(Z)-v-ethyI enoldiazoacetate with diaziridine.
