Hydrogenated naphthalene derivatives

Cationic Planar Chiral Palladium P,S Complexes as Highly Efficient Catalysts in
Enantioselective Ring Opening of Oxa- and Azabicyclic Alkenes. — The reac45- 112 the
tion of oxa- and azanorbornadiene derivatives with dialkylzinc compounds (III) or (V)
in the presence of the title catalysts affords dihydronaphthols and dihydronaphthylamines with high enantiomeric excesses. In general, a low catalyst loading is sufficient
to reach complete conversion within a short reaction time (10-30 minutes). By variation
of the reaction conditions, nonaromatic oxabicycle (VII) can be converted into cyclohexenol (VIII) with high enantioselectivity. — (CABRERA, S.; GOMEZ ARRAYAS,
