Seven novel palladium complexes of the type [Pd(HL)Cl2] and [Pd(L)Cl] containing chiral pinane ligands (HL = 3-[(2-aminoethyl)imino]-pinane-2-ol; 3,3′-(ethylenediimino)bis-pinane-2-ol; cis-3-(2-aminoethylamino)-pinane-2-ol; cis-3,3′(ethylenediamino)bis-pinane-2-ol; trans-3,3′(ethylenediamino)bis-pinane-2-ol; 3-[2-(2-hydroxybenzylamino)ethylamino]-pinane-2-ol; L = 3-[2-(3,5-di-tert-butyl-2-hydroxybenzylidene)aminoethylimino]pinane-2-ol) were synthesized in good yields from the direct reaction of chiral nitrogen ligands with Li2PdCl4 in MeOH. These synthesized complexes were characterized by means of elemental analysis, FT-IR, multidimensional and multinuclear NMR spectroscopic methods.

2-Amino-2-(trifluoromethoxy)butanoic acid (O-trifluoromethyl homoserine) was synthesized as a racemate and in both enantiomeric forms. The measured pKa and log D values establish the compound as a promising analogue of natural aliphatic amino acids.

In this study, we synthesized five new chiral ligands from (+) and (-)-α-pinene, which were successfully employed in the stereoselective addition of diethylzinc to aldehydes, leading to secondary chiral alcohols in up to 99% yield and 94% e.e.
