S ince publishing our original manuscript, a few errors have been brought to our attention. The references in Scheme 1 were inverted. A corrected scheme is shown below. Additionally , the text accompanying Table 3 refers to the substrate as a 3-methylthiophene; it is actually a 4-methylthiophene. Finally, two names were misspelled in the references section.(More)
A novel protocol for the regioselective intermolecular amination of various arenes has been developed. By using an I(III) oxidant in the presence of a Au(I) catalyst, a direct and novel route for regioselectively accessing a variety of substituted aniline moieties has been achieved with yields as high as 90%. Mechanistic insight suggests that(More)
The iron-catalyzed arylation of aromatic heterocycles, such as pyridines, thiophenes, and furans, has been achieved. The use of an imine directing group allowed for the ortho functionalization of these heterocycles with complete conversion in 15 min at 0 °C. Yields up to 88% were observed in the synthesis of 15 heterocyclic biaryls.
The development of a β-CCT-lanthanide conjugate that binds the dopamine transporter (DAT) with high affinity (K(d) = 303 nM) is described. Contrast agents such as the one described herein could be used as molecular probes to directly study the binding of small molecules to receptors such as DAT via MRI, PET or SPECT.
The Hyperpolarized gas Chemical Exchange Saturation Transfer (HyperCEST) Magnetic Resonance (MR) technique has the potential to increase the sensitivity of a hyperpolarized xenon-129 MRI contrast agent. Signal enhancement is accomplished by selectively depolarizing the xenon within a cage molecule which, upon exchange, reduces the signal in the dissolved(More)
