  Parallel fluorous biphasic synthesis of 3 H -quinazolin-4-ones by an Aza-Wittig reaction employing perfluoroalkyl-tagged triphenylphosphine

  摘要：

  A perfluoroalkyl-tagged triphenylphosphine eras applied in a fluorous biphasic system for the efficient parallel synthesis of 3H-quinazolin-4-ones via an Aza-Wittig reaction. The products were isolated by solid-phase extraction on fluorous reversed-phase silica gel. A new solid-phase bound phosphine derivative was used for comparison and yielded similar results.

  new 4(1H)-quinazolinones were synthesized and evaluated in the carrageenin-induced paw edema test. Most of the compounds were obtained by the cyclization of the appropriately substituted anthranilamides with acid chlorides, followed by further chemical transformation. Structure-activity data suggest that 2-isopropyl-1-phenyl-, 2-cyclopropyl-1-phenyl-, and 1-isopropyl-2-phenyl-4(1H)-quinazolinones afford

  The regiospecific C-2–H arylation of N-3-substituted quinazolin-4(3H)-ones with a wide range of aryl or (hetero)aryl halides under microwave irradiation was studied. A ligand-dependent palladium/copper bicatalytic system was developed and allowed direct cross-coupling with a variety of (hetero)aryl halides. This useful and scalable procedure promotes the construction of C(sp2)–C(sp2) bonds from arenes

  describe the direct synthesis of quinazolinones via cross-dehydrogenative coupling between methyl arenes and anthranilamides. The C–H functionalization of the benzylic sp3 carbon is achieved by di-t-butyl peroxide under air, and the subsequent amination–aerobic oxidation process completes the annulation process. Iron catalyzed the whole reaction process and various kinds of functional groups were tolerated
