摘要:The present invention provides complex compounds reminiscent of natural products and libraries thereof, as well as methods for their production. The inventive compounds and libraries of compounds are reminiscent of natural products in that they contain one or more stereocenters, and a high density and diversity of functionality. In general, the inventive libraries are synthesized from diversifiable scaffold structures, which are synthesized from readily available or easily synthesizable template structures. In certain embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from a shikimic acid based epoxyol template. In other embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from the pyridine-based template isonicotinamide. The present invention also provides a novel ortho-nitrobenzyl photolinker and a method for its synthesis. Furthermore, the present invention provides methods and kits for determining one or more biological activities of members of the inventive libraries. Additionally, the present invention provides pharmaceutical compositions containing one or more library members.

标 题 :Synthesis of diethynylbenzene
发明人：CAROSINO LAWRENCE E; HERAK DAVID C
权利人:HERCULES INC
摘要:The invention provides an inexpensive synthesis process for preparation of diethynylbenzene monomers that are useful in the preparation of polyacetylenes. This process provides for the preparation of thermally sensitive monomers in a one-pot reaction using readily available materials at low temperatures in an environment capable of absorbing large amounts of energy. Divinylbenzene is first brominated and then dehydrobrominated with sodium hydroxide or potassium hydroxide preferably in the presence of a phase transfer agent followed by distillation to recover the diethylnylbenzene product.

权利人:UNIV NORTH CAROLINA STATE
摘要:A method of making a bacteriochlorin is carried out by condensing a pair of compounds of Formula II n nto produce the bacteriochlorin, wherein R is an acetal or aldehyde group. The condensing may be carried out in an organic solvent, preferably in the presence of an acid. The bacteriochlorins are useful for a variety of purposes such as active agents in photodynamic therapy, luminescent compounds in flow cytometry, solar cells, light harvesting arrays, and molecular memory devices.
