  Synthesis of a New Diaminodithiol Bifunctional Chelator for Radiolabeling Biomolecules with Indium(III)

  摘要：

  The synthesis of a new bifunctional ligand 1-(p-carboxybenzyl)-N,N'-bis-[1,1-dimethyl-1-(p-methoxybenzylthio)ethyl]-ethylenediamine-N,N'-diacetic acid, di-t-butyl ester (1, nbi6ss) is described. It consists of a carboxybenzyl group substituted on a carbon atom of the ethylenediamine moiety of a hexadentate ligand, which has been found to have a very high affinity for In(III). The gem-dimethylthiol groups and the carboxylic acid groups of the ligand were protected by groups that can be removed under mild conditions after conjugation to a peptide or protein.

  stereoselective Diels–Alder reactions with olefinic azlactones by asymmetric trienamine catalysis. The obtained cycloadducts are easily transformed into the corresponding cyclic α,α‐disubstituted N‐protected amino acid methyl esters under mild reaction conditions. Furthermore, it is demonstrated that in situ ligation of the crude cycloaddition products with amino acid hydrochloride salts leads to the

• Cross-trienamines in Asymmetric Organocatalysis
  作者：Kim Søholm Halskov、Tore Kiilerich Johansen、Rebecca L. Davis、Marianne Steurer、Frank Jensen、Karl Anker Jørgensen

  DOI：10.1021/ja3068269

  日期：2012.8.8

  Cross-conjugated trienamines are introduced as a new concept in asymmetric organocatalysis. These intermediates are applied in highly enantioselective Diels-Alder and addition reactions, providing functionalized bicyclo[2.2.2]octane compounds and gamma'-addition products, respectively. The nature of the transformations and the intermediates involved are investigated by computational calculations and NMR analysis.
