The chemistry of copper is extremely rich because it can easily access Cu0, CuI, CuII, and CuIII oxidation states allowing it to… Expand A great number of structurally diverse natural products containing five-membered heterocyclic subunits, such as imidazole… Expand The first efficient intermolecular reaction of gold carbene intermediates generated via gold-catalyzed alkyne oxidation has been… Expand The substrate scope, the mechanistic aspects of the gold-catalyzed oxazole synthesis, and substrates with different aliphatic… Expand A facile type of one-pot, transition-metal-free domino process was developed for the synthesis of oxazoles. Thus, a variety of… Expand A new method for the direct, copper-catalyzed arylation of heterocycle C−H bonds by aryl halides has been developed. In addition… Expand 2,5-Disubstituted oxazoles are synthesized from the corresponding propargylcarboxamides under mild reaction conditions via… Expand [formula: see text] A mild and highly efficient cyclization of beta-hydroxy amides to oxazolines is described using DAST and… Expand Esherichia coli microcin B17 is a posttranslationally modified peptide that inhibits bacterial DNA gyrase. It contains four… Expand The synthesis, proof of structure, and the absorption and fluorescence properties of two new unsymmetrical cyanine dyes, thiazole… Expand
