investigating the substitution pattern depending regioselectivity of enantioselective BINOL-Ti-catalyzed Diels–Alderreactions of juglone-based dienophiles with 1-oxygenated dienes is reported. The different influences of residues both on the diene as well as on the dienophiles are investigated giving a detailed picture of their role on the regioselectivity. A mechanistic study investigating the substitution
