## Abstract The mono‐oxime and dioxime of the title compound have been prepared.
## Abstract Oxidation of the title compound with __m__‐chloroperbenzoic acid affords a keto‐lactone, two bis‐lactones and a bis‐spirolactone, in varying amounts depending upon the reaction conditions. The structures were established by means of X‐ray diffraction, ^1^H‐ and ^13^C‐NMR spectroscopy.
## Abstract Each of the three isomeric[4.3.3]propellane‐8,11‐diols was lactonized by using 1, ω‐diacids of different chain lengths. The minimal chain length required to bridge the __syn__‐__syn__ diol is –CO(CH~2~)~11~CO–.
## Abstract The bis[6.3.3]propellane 6 derivative of 2,2′,6,6′‐tetramethylbiphenyl was, in the final stage, synthesized by dehydration, of octaalcohol 5. X‐ray structure analysis revealed the highly symmetric shape of the molecule and disordered oxygen atoms in the tetrahydrofuran rings. The dihedr
