Patent number: 5397563Abstract: Accordingly, the present invention is directed to biological compounds derivatized so as to contain at least one perfluoro-t-butyl moiety for use in fluorine-19 NMR and/or MRI studies. The perfluoro-t-butyl (PFTB) moiety, ##STR1## is an excellent reporter group for fluorine-19 NMR/MRI. It is a source of nine magnetically equivalent fluorine nuclei which generate a single intense resonance for easy detection in spectroscopy or imaging. This signal is a sharp singlet, not split by neighboring nuclei or spread over a wide frequency range and eliminates any chance of ghost images which might arise from multiple resonances. These spectral properties ensure a maximum signal-to-noise ratio (S/N) for readily detecting this moiety. The foregoing allows either reduction in the concentration of the derivatized compound, ability to use MRI instruments with lower field strengths, a reduction in imaging times, or a combination of the foregoing as a result of this moiety producing a single, sharp, intense resonance.Type: GrantFiled: March 1, 1994Date of Patent: March 14, 1995Assignees: The Johns Hopkins University, Towson State UniversityInventors: Walter J.

Patent number: 5319115Abstract: This invention provides a simplified method for converting pregnan-3,20-dione compounds to 3.alpha.-hydroxy,3.beta.-substituted-pregnanes. By selective use of reagents the unprotected dione is converted chemoselectively and diastereoselectively into a 3(R)-pregnan-3-spiro-2'oxirane-20-one intermediate. This intermediate can then be converted regioselectively by a second set of reactions to the 3.alpha.-hydroxy,3.beta.-substituted-20-one form, which can be further modified at the 20-keto position.Through this method, each ketone group is independently treated. By modifying the ketones one at a time, one can obtain the desired stereo-specificity at each site.Type: GrantFiled: March 4, 1992Date of Patent: June 7, 1994Assignee: Cocensys Inc.Inventors: Hasan Tahir, Michael Bolger, Richard Buswell, Richard Gabriel, Jay Stearns
