Effect of co-ligands on chemical and biological properties of (99m)Tc(III) complexes [(99m)Tc(L)(CDO)(CDOH)2BMe] (L=Cl, F, SCN and N3; CDOH2=cyclohexanedione dioxime).

Nucl. Med. Biol. 41(10) , 813-24, (2014)

(99m)Tc-Teboroxime ([(99m)TcCl(CDO)(CDOH)2BMe]) is a member of the BATO (boronic acid adducts of technetium dioximes) class of (99m)Tc(III) complexes. This study sought to explore the impact of co-lig...

Asymmetric bromolactonization using amino-thiocarbamate catalyst.

J. Am. Chem. Soc. 44th ed., 132 , 15474-15476, (2010)

A novel amino-thiocarbamate-catalyzed bromolactonization of unsaturated carboxylic acids has been developed. The scope of the reaction is evidenced by 22 examples of γ-lactones with up to 99% yield an...

Enantioselective bromoaminocyclization using amino-thiocarbamate catalysts.

J. Am. Chem. Soc. 133 , 9164-9167, (2011)

A facile and efficient enantioselective bromoaminocyclization of unsaturated sulfonamides has been developed using an amino-thiocarbamate catalyst. A range of enantioenriched pyrrolidines were prepare...
