We report here new investigations of the CD of TDKPs (including new structural types). Some unprecedented rules between ACs and CD spectra are deduced from the studies of experimental and calculated CD of them as follows: (1) the CD band around 270 nm could be applied to determine the ACs of the chiral carbons at α/α′ positions in TDKPs. (2) The intensities of CE around 270 nm followed the decreasing...
