The absolute configurations of cis,trans- and trans,trans-2,2′-spirobi-indane-1,1′-diols were non-empirically determined by applying the c.d. exciton chirality method to their bis[(p-dimethylamino)benzoates].
Absoluteconfiguration and enantiomericpurities of some hydroxy-ketones and diols of spiro[4.4]nonane and 2,2′-spirobi-indan can be simultaneously determined by use of MTPA derivatives and a lanthanoid shift reagent.
