Hierarchical helicates based on ketone-substituted titanium(IV)triscatecholates show different monomer-dimer behavior depending on different solvents. The dimerization constants of a whole series of differently alkyl-substituted complexes is analyzed to show that the solvent has a very strong influence on the dimerization. Hereby, effects like solvophobicity/philicity, sterics, electronics of the substituents and weak side-chain—side-chain interactions seem to act in concert.
SYNTHESIS OF ANSAMYCINS: AN APPROACH TO THE NAPHTHOQUINONE PORTION OF THE RIFAMYCINS AND STREPTOVARICINS

Naphthoquinone 1, a fully functionalized model for intermediates in ansamycin synthesis, was prepared by the intramolecular Claisen condensation of benzofuran 9 followed by oxidation of the novel tricyclic compound 10.
