Iw. Davies et al., THE INFLUENCE OF LIGAND BITE ANGLE ON THE ENANTIOSELECTIVITY OF COPPER(II)-CATALYZED DIELS-ALDER REACTIONS, Chemical communications, (15), 1996, pp. 1753-1754
Novel spirobis(oxazolines) provide excellent levels of stereocontrol i
n copper-catalysed Diels-Alder reactions; the larger the ligand bite a
ngle the higher the enantioselection (up to 98.4% ee).
