Deltacyclene (tetracyclo[4,3,0,02,903,7]non-4-ene was stereoselectively hydroformylated to exo-formyl-deltacyclane in the presence of rhodium and platinum catalysts. In the case of optically active bisphosphines up to 22% e.e-s were achieved.

Preparative methods are proposed for the production of 5-brexanone and the acetates of 2-brendanol and 2-noradamantanol from cis-bicyclonona-3,7-diene.Dehydration of 5-brexanol and 2-brendanol gave 4-brexene and deltacyclane respectively.The (13)C NMR spectra of the compounds of the noradamantane, brexane, brendane, and deltacyclane series were studied.

The brexane skeleton functionalized at C-5 is perceived as potentially usefull for various machanistic studies.Our present objective was to prepare and characterize brex-5-yl derivatives and to seek spectroscopic evidence for geometric distortion in the skeleton.The structures synthesized include brex-4-ene, brex-5-one, both of the epimeric brexan-5-ols, and various derivatives of these compounds.Spectroscopic data ( ir, 1H nmr, and uv ) are compared with those from relevant model compounds and are most simply interpreted on the basis of a twist in the brexyl skeleton.This distortion imparts more exocharacter to the C-H bonds at C-4 and more endo character to the C-H bonds at C-5.As an extension of the useful terms geminal and vicinal, we propose the word hominal to represent a 1,3-relationship between two groups.
