  • Patent number: 8052961
    Abstract: Disclosed are compounds having the structure: wherein R1a and R1b are independently H, alkyl, F, or fluoroalkyl; wherein R2a, R2b, R2a?, and R2b? are independently H, alkyl, F, fluoroalkyl, aryl, or alkenyl; wherein R3 is OH, alkoxyl, NH2, alkylamino, or dialkylamino; wherein R4a and R4b are independently H, alkyl, acyl, or alkyloxycarbonyl; wherein R11, R12, R13, R21, R22, and R23 are independently H, alkyl, F, or fluoroalkyl; and wherein C0, C1, C2 and C2? are independently chiral or achiral. Also disclosed are processes for making a fluorinated ?-amino acid comprising the steps of: providing a diol; treating the diol with a thionyl halide with oxidative workup; reacting the product with an azide salt to yield an azido group; oxidizing the product to yield a carboxyl group; and reducing the azido group to yield an amino group.

  • Publication number: 20110217241
    Abstract: Compositions for producing multi-chromic (“color”) magnetic resonance images (MRI). The compositions for use as MRI imaging agents include a magnetic resonance imaging tracer having a signal emitter, such as a 19F imaging tracer (19FIT), conjugated with a magnetic signal modulator, such as a paramagnetic functional group or a paramagnetic ion. The 19FIT and the signal modulator (M) are joined covalently by a chelator such as DOTA, forming a nanometer-sized fluorinated paramagnetic complex 19FIT-DOTA-M. Other signal emitters, such as 31P imaging tracer (31PIT), can also be modulated using this strategy (i.e., 31PIT-DOTA-M) to generate multi-chromic 31P MRI or MRS.

  • Publication number: 20100099845
    Abstract: Disclosed are processes for preparing a protected trifluorothreonine, or salt thereof or carboxylate derivative thereof, the process comprising: dihydroxylation of an alkene to yield a dihydroxyl compound; conversion of the dihydroxyl compound to a monohydroxyl compound; protection of the monohydroxyl compound to yield an azide compound; transformation of the azide compound to yield an amino compound; protection of the amino compound to yield a protected amine compound; and oxidation of the protected amine compound to yield the protected trifluorothreonine. Also disclosed are compounds having the structure: or salt thereof or carboxylate derivative thereof, wherein P2 is a hydroxyl protecting group, and wherein P3 is an amine protecting group. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
