Sourcing large numbers of lead-like compounds is a major challenge; a unified synthetic approach enabled the efficient synthesis of 52 diverse lead-like molecular scaffolds from just 13 precursors.
Primary hydroxylamines, RNHOH, decompose readily in the presence of transition metal ions. We show that this reactivity can be arrested by ligand design via an intramolecular hydrogen bond. Six metal complexes with an intact NHOH group were synthesized and crystallographically characterized. The Cu–hydroxylamine complexes can catalyze the aerobic oxidation of benzylic alcohols.

tetraazatriacetic compound, which is a rigidified derivative of PCTA12 ligand with a cyclohexylene bridge replacing an ethylene one, was prepared. Two synthetic routes have been investigated, both of them implying a common functionalized triamine intermediate. Whatever the route, four synthetic steps were necessary to obtain the target tricyclic ligand. The more effective one (Route B) led to the desired compound

An unsymmetric ligand bearing a salicylimine side and a 2-nitrobenzenesufonamide side has been synthesized in two simple steps. Complexations with Cu(II), Fe(III) and Co(II) - which oxidizes to Co(III) once complexed - indicate that the ligand can be either bidentate or tridentate depending on the geometric preferences of the metal ion and whether the sulfonamide is deprotonated. The obtained crystal structures are also stabilized via hydrogen bonds and pi-pi stacking interactions. Crown Copyright (c) 2013 Published by Elsevier B.V. All rights reserved.
