Abstract The title compounds 26 and 32 were prepared by systematic mono-and bisanellation of sixmembered rings to the positions 5, 6 and 5′, 6′, resp. of 2, 2′- spirobiindane. SE acylation and subsequent transformations of the acylgroups afforded many derivatives with substituents in positions 4 and 4′ of the parent compounds which were required for testing semiempirical values of chirality functions. 5, 6, 7, 8- ...
