The chirality transfer from CD-silent secondary alc. (inductor) to the stereodynamic bichromophoric di(1-naphthyl)methane probe (reporter) led to the generation of intense induced exciton-type Cotton effects in the UV/VIS absorption region. The di(1-naphthyl)methane probe exhibits extraordinarily high sensitivity to even small structural variations of the alc. skeleton, i.e., the probe is able to distinguish between an oxygen atom and a methylene group in a 3-hydroxytetrahydrofurane skeleton. Signs and amplitudes of the exciton couplets of 1Bb electronic transition might be correlated with the type of stereo differentiating parts of the mol., flanking the stereogenic center, however, not with the absolute configuration. The origin of the induced Cotton effects was established by means of exptl. and theor. methods. As a result, a mechanism of chirality transfer from permanent stereogenic center to the bichromophore is proposed.
