Two methods for remote aromatic C-H oxygenation reactions, have been developed. Method1, the Cu-catalyzed oxygenation reaction, is highly efficient for cyclization of electron-neutral and electron-rich biaryl carboxylic acids into 3,4-benzocoumarins. Method2, the K2S2O 8-mediated oxygenation reaction, is more general and practical for cyclization of substrates with electron-donating and -withdrawing groups (see scheme). Copyright

The present invention relates to a compound with aryl-amidines, particularly amidinoaryl-cyclopropanes, amidinoarylmethyl-pyrroles, amidinoaryl-benzenes, amidinoaryl-pyridines, or amindonoaryl-alanines, represented by formula (1), a pharmaceutically acceptable salt, a prodrug, a hydrate, a solvate or an isomer thereof, which are inhibitors of coagulation enzyme, factor Xa (FXa). The present invention also relates to a pharmaceutical composition containing the compound, and a method of using the same as an anticoagulant agent for treatment and prevention of thrombosis disorders.

A practical synthesis of 2-carboxyphenylboronic from 2-tolylboronic acid and aqueous potassium permanganate under mild conditions is reported. The title compound couples with aryl bromides containing electron-withdrawing groups to give biaryl-2-carboxylic
Benzyne formation and the stepwise decomposition of benzenediazonium-2-carboxylate: A re-investigation

A study of the decomposition reactions of benzenediazonium-2-carboxylate, carried out in a number of mixed nucleophilic solvents, shows that a number of mechanistic pathways can operate simultaneously and can afford, in addition to products derived from benzyne, products derived from the 2-carboxyphenyl cation and the 2-carboxyphenyl radical: benzyne formation is favoured in halogenated solvents and occurs by the concerted loss of nitrogen and carbon dioxide.
