摘要：
A highly sterically hindered C-2-symmetric chiral pyridine derivative (3) was synthesized from 1,5-diketone (2) by the action of NH4OAc/Cu(OAc)(2) in refluxing propionic acid. The pK(a) of 3 was determined to be 6.26 and the structure was characterized by X-Ray crystallographic analysis of its triflic acid salt.
