Monoselective γ-C-H olefination and carbonylation of aliphatic acids has been accomplished by using a combination of a quinoline-based ligand and a weakly coordinating amide directing group. The reaction provides a new route for constructing richly functionalized all-carbon quaternary carbon centers at the β-position of aliphatic acids.
A new efficient synthesis of pyranoquinolines from 1-acetyl N-aryl cyclopentanecarboxamides

, p. 3651 - 3653 (2008/02/12)
A new efficient synthesis of pyrano[2,3-b]quinoline derivatives is developed via the H2SO4-mediated tandem cyclization/ring-opening/recyclization reaction of readily available 1-acetyl N-aryl cyclopentanecarboxamides, during which a
