The absolute configuration of the 2‐(phenylmethyl)pyridine derivatives 1 – 9 had been established by X‐ray diffraction and chemical correlation. Their CD spectra have been studied in different solvents for the free and protonated forms. It has now been found that, from the sign of the strong CD couplet between 270 and 220 nm, which was observable for all these compounds besides 7 and 9 , their absolute configuration can be determined much quicker.
