Under anhydrous conditions and with a 3∶1 molarity ratio of α-methylbenzylamine to 2-naphthol, a fair enantioselection has been observed（up to 80.6% ee）.展开更多

The process is easy to handle and less time-consuming. The yields were about 38 % with 98 % optical purity.展开更多
Reaction of ( S) α methylbenzylamine with Pd(OAc) 2 in anhydrous HOAc produced the chiral complex [Pd( μ O 2CMe)( S C 6H 4CHMeNH 2)] 2 (1).

The complex was characterized by 1H NMR spectroscopy, elemental analysis and a single crystal X ray analysis. The X ray crystal structure analysis revealed that complex 1 has four isomers: two outer and two inner isomers.展开更多
