Abstract: The present application discloses methods for the production of organic compounds comprising a linear series of five fused carbon rings. Such compounds are useful in the production of electronic components, devices and materials. For example the methods disclosed permit the production of 2,9- and 2,10-disubstituted pentacene compounds and 2,6,9,13- and 2,6,10,13-tetrasubstituted compounds that present particularly advantageous properties for the manufacture of semiconductor materials, and may be used in devices such as for example thin film transistors and solar cells. These features are enhanced by ?-? parallel stacking in the solid state. Also disclosed are compounds that are excellent candidates for use in the manufacture of semiconductor materials, and other components of electronic systems, by virtue of their solubility, crystal packing geometries, and electronic properties.

Abstract: The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetra-cycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-pro liferative agents in the treatment of diseases of humans or other animals.
