The crystal structure of 14-oxo-13,14-seco-5α-cholest-13(18)-en-3β-yl acetate (2), obtained (in addition to the (E)-Δ12-isomer 3) by oxidative fragmentation of the C(13)-C(14) bond of 14α-hydroxy-5α-cholestan-3β-yl acetate (1), was determined by X-ray analysis. In addition, the configurations of the acetoxy derivatives 4-6, formed by the thermal lead tetraacetate oxidation of 1, were deduced from the relevant 1H-NMR parameters.
Kristalna struktura 14-okso-13,14-seko-5α-holest-13(18)-en-3β-il-acetata (2). koji se dobiva (pored (E)-Δ12-izomera 3) oksidativnom fragmentacijom C(13)-C(14) veze 14α-hidroksi-5α-holestan-3β-il-acetata (1) određena je analizom X-zraka. Pored toga, konfiguracije njegovih acetoksi derivata 4-6, koji se grade pri termičkoj olovo-tetraacetatnoj oksidaciji, izvedene su na osnovu odgovarajućih 1H-NMR parametara.
