Cationicnitrileplatinum(II) complexes of formula [PtMe(RCN)(bipy)]+ undergo nucleophilic addition of carbanions −CH(COX)(COY) (X, Y= Me, OMe), −CH(CO2Me)CN and −CH(CN)2 to afford neutral products. According to the nature of the nucleophile, the organic ligand fragment displays either an imino enol or an enamine isomeric structure. The Pt−N bond can be cleaved upon reaction with acids with formation

An efficient synthesis has provided access to a novel alpha-tocopherol analogue (2), as well as its trifluoroacetate salt and acetate ester. An annulation reaction was used to establish the pyridinol core structure and a Stille coupling reaction was employed for conjugation with the tocopherol side chain. This analogue was shown to suppress the levels of reactive oxygen species in cultured cells, and to quench peroxidation of mitochondrial membranes. (C) 2010 Elsevier Ltd. All rights reserved.
