Scope of the Suzuki−Miyaura Cross-Coupling Reactions of Potassium Heteroaryltrifluoroborates
摘要:
A wide variety of bench-stable potassium heteroaryltrifluoroborates were prepared, and general reaction conditions were developed for their cross-coupling to aryl and heteroaryl halides. The cross-coupled products were obtained in good to excellent yields. This method represents an efficient and facile installation of heterocyclic building blocks onto preexisting organic substructures.
The present invention relates to substituted heterocyclic compounds of Formula I or XI:
or pharmaceutically acceptable salts or N-oxides or quaternary ammonium salts thereof wherein constituent members are provided hereinwith, as well as their compositions and methods of use, which are histamine II4 receptor inhibitors useful in the treatment of histamine II4 receptor-associated conditions or diseases or disorders including, for example, inflammatory diseases or disorders, pruritus, and pain.
Compound of the formula: (I) [wherein each of X
