• AgONO-Assisted Direct CH Arylation of Heteroarenes with Anilines
  作者：Saravanan Gowrisankar、Jayasree Seayad

  DOI：10.1002/chem.201403640

  日期：2014.9.26

  A novel copper‐catalyzed CH arylation of heteroarenes with anilines by an in situ diazonium reaction is established by using silver nitrite (AgONO) as an unconventional nitrosating reagent under acid‐free conditions. It provides a complementary approach for the CH arylation of electron‐rich heteroarenes with aromatic amines affording a variety of heterobiaryls in moderate to good yields.

• Nonpeptide Angiotensin II Receptor Antagonists. Synthesis, in vitro Activity, and Molecular Modeling Studies of N-[(Heterobiaryl)methyl]imidazoles

  With the aim of explaining the influence of the structural changes on the biphenylic moiety on the activity, a series of N-[(heterobiaryl)methyl]imidazoles (I), constructed on the model of DuPont compounds by replacing either the central or terminal phenyl ring with a heteroaromatic one, such as furan, thiophene, thiazole, and pyridine, was synthesized. Compared to the reference DuPont compound (EXP-7711), all the heterobiaryl derivatives showed a reduced potency both in receptor binding (rat adrenal capsular membranes) and in the functional assay (angiotensin II-induced contraction of rabbit aorta strips). The lower activity was justified by the extensive molecular modeling studies, which took into consideration the conformational and electrostatic features of several heterobiaryl derivatives. On the basis of the results obtained, it was hypothesized that the central aromatic ring of the biarylic portion works as a spacer, orienting in the right way the terminal phenyl ring, whose electronic distribution is, instead, crucial to its fitting well with a lipophilic pocket at the receptor site.
