A series of new boron-containing amino acids 1-HOOCCH(NH2)(CH2)(n)S-1,2-C2B10H11 (n = 4-6) was prepared by alkylation of 1-mercapto-ortho-carborane with omega-bromoalkylacetamido diethylmalonates followed by acid hydrolysis and decarboxylation. Mild deboronation of the c/oso-carborane cage with CsF gives cesium salts of the corresponding nido-carborane based amino acids Cs[7-HOOccH(NH2)(CH2)(n) S-7,8-C(2)B9H(l1)] d (n = 4-6). The compounds synthesized can be used in radionuclide diagnostics and boron neutron capture therapy of cancer(C) . 2013 Elsevier Ltd. All rights reserved.
