ligands in the enantioselectiveoxidative biaryl coupling of substituted 2-naphtholderivatives. Under the optimal conditions employing 2.5-10 mol % of a 1,5-diaza-cis-decalin copper(II) catalyst with oxygen as the oxidant, enantioselectivecouplings (44-96% ee) could be achieved for a range of 3-substituted 2-naphthols including the ester, ketone, phosphonyl, and sulfonyl derivatives. The relationship
The Mannich reactions of some 2-naphthol and its tetrahydro compounds were studied. The Mannich reaction of 2-naphthol (I) by morpholine gave 1-(morpholinomethyl) compound (II), which was also obtained by same reaction of 2-hydroxy-1-naphthoic acid (V). On the other hand, the Mannich reaction of 2-tetralol (XVI) gave 3-(morpholinomethyl) derivative (XV). 2-Hydroxy-3-naphthoic acid (VI) and its tetrahydro compound (IX) were introduced into 1-(morpholinomethyl) derivatives, XVII and XIX, respectively. Some transformations of these Mannich compounds were also studied.

analyzed by NMR, X-ray and DFT calculations. In aprotic solution the molecules contain intramolecular OHO hydrogen bonds, which change into intermolecular ones in solid state. The energy barriers for the amide group rotation around the CN bond were estimated from the lineshapeanalysis of (1)H and (13)C NMRsignals. A tentative correlation between the barrier height and the strength of OHO bond was proposed
