Condensation reactions to form oxazoline-substituted potassium organotrifluoroborates.


ABSTRACT: A library of oxazoline-substituted potassium organotrifluoroborates was prepared via the condensation of various potassium formyl-substituted aryl- and heteroaryltrifluoroborates with tosylmethyl isocyanide under basic conditions. The efficient Suzuki-Miyaura cross-coupling of products thus formed to various aryl bromides was achieved in good yields. The method allows the facile preparation of oxazole-containing triaromatic products in two steps from simple potassium formyl-substituted aryl- or heteroaryltrifluoroborates.
