Influence of 11-trimethylsilyloxy- or 11-hydroxy-substituents on the electron-impact-induced fragmentation of trimethylsilyl derivatives of some androstanols

open access: closedJournal of the Chemical Society, Perkin Transactions 1, 1973
The mass spectra of the trimethylsilyl derivatives of some androstanes containing an 11-hydroxy-substituent exhibit several prominent and characteristic ions containing the trimethylsilyl group. The mechanisms of formation of these ions have been investigated with the aid of high-resolution mass spectrometry and deuterium, 18O, and ...

Steroide, 28. Darstellung von Steroidhormon‐Analogen aus 2.3 β‐Imino‐5α‐androstanol‐(17β) und 3α‐Chlor‐2 β‐amino‐5α‐androstanol‐(17 β)

open access: closedChemische Berichte, 1971
Abstract2.3β‐Imino‐5α‐androstanol‐(17β) (2a) wurde aus 2.3α‐Epoxy‐5α‐androstanon‐(17) über den entsprechenden Azidoalkoholsulfonsäureester synthetisiert und zu 3α‐Chlor‐2β‐amino‐5α‐androstanol‐(17β) (3) umgesetzt. Aus diesen beiden Verbindungen wurden Oxazoline, Thioxothiazolidine, Aminoalkohole und Aminothiole dargestellt.

Orientation and vertical fluctuations of spin-labeled analogues of cholesterol and androstanol in phospholipid bilayers

open access: closedBiochimica et Biophysica Acta (BBA) - Biomembranes, 1987
We have used ESR and NMR linewidth broadening by spin-labels to determine the overall orientation of spin-labeled analogues of cholesterol and androstanol in egg lecithin bilayers. While the cholesterol analogues were found to have a single orientation in each monolayer, with the acyl chain pointing towards the center of the bilayer, the androstanol ...
