Five dehydrated compounds obtained from a tert-butyldimethylsilylchloride/imidazole or an aqueous hydrochloric acid treatment of 17 alpha-butyl-3-O-methyl estradiol in refluxing solvent were purified and characterized. Three compounds were obtained from a direct vicinal proton elimination, the two others from a vicinal
D C Landrum et al.
Journal of chromatography, 483, 21-32 (1989-12-08)
The use of gas-liquid chromatography and mass spectrometry with derivatizing agents that give stable derivatives and consistent fragmentation patterns allows for accurate identification of a variety of compounds. In this study either N-methyl-N-tert.-butyldimethylsilyltrifluoroacetamide or N-tert.-butyldimethylsilylimidazole were employed to derivatize a
