The present study is concerned with the kinetics of oxidation reaction of bis(2,2′,6′,2″-terpyridine)iron(II) by bromate and periodate in sulphuric acid medium by spectrophotometric method. The order of the reaction is unity both in the substrate and the oxidant. The oxidation process is catalysed by sulphuric acid and the rate increases with hydrogen ion concentration. Ionic strength has a positive salt effect on the rate. Probable mechanisms were suggested and the specific rate constants were evaluated.

The first stereoselective total synthesis of polyacetylene panaxjapyne C is described. The key reactions include regioselective opening of the epoxide and Cadiot-Chodkiewicz cross-coupling reactions. l-Ascorbic acid was used as a chiral pool material for the construction of the both terminal acetylenes. © 2012 Elsevier Ltd.

The stereoselective total synthesis of (-)-achaetolide is described in a convergent manner. Grignard addition, Wittig homologation, acetate aldol and ring closing metathesis reactions were the key steps involved. The required olefinic alcohol fragments were synthesized from a single chiral pool material 2-deoxy-d-ribose and olefinic acid fragment was prepared from acetate aldol reaction. Both the olefinic acid and alcohols were prepared in a concise method. © 2012 Elsevier Ltd. All rights reserved.
