  New trisubstituted cyanopyrazoles and cyanoscorpionates

  摘要：

  New syntheses are reported to give pyrazoles with cyano substituents at the 4-position of the pyrazole ring and ethyl or isopropyl substituents at the 3-position, as well as pyrazoles with cyano substituents at the 4-position and alkyl/aryl/bromo substituents at both the 3-and 5-positions. Synthesis of scorpionates using tetradecane as a high-boiling solvent has been shown to be more efficient than the melt method and has led to new scorpionates using the newly synthesized pyrazoles. An unexpected complex is isolated in which the Ni(cyclam)2(+) moiety crystallizes with two cyanoscorpionates as counterions, without binding of the scorpionate ligands to the Ni atom.

  A facile iterative synthesis of 2,5-terpyrimidinylenes that are structurally analogous to alpha-helix mimics is presented. Condensation of amidines with readily prepared alpha,beta-unsaturated alpha-cyanoketones gives 5-cyano-substituted pyrimidines. Iterative transformation of the 5-cyano group into an amidine allows synthesis of 2,5-terpyrimidinylenes with variable groups at the 4-, 4'-, and 4 ''-positions. These compounds are designed to mimic the i, i + 4, and i + 7 sites of an alpha-helix.
