  Pyrazolo[1,5-a]pyrimidin-7-yl phenyl amides as novel antiproliferative agents: Exploration of core and headpiece structure–activity relationships

  摘要：

  A novel series of antiproliferative agents containing pyrazolo[1,5-a]pyrimidin-7-yl phenyl amides, selective for p21-deficient cells, were identified by high-throughput screening. Exploration of the SAR relationships in the headpiece, core, and tailpiece is described. Strict steric, positional, and electronic requirements were observed, with a clear preference for both core nitrogens, a thienoyl headpiece, and meta substituted tailpiece. (c) 2007 Elsevier Ltd.

Through cyclopropanation of bench-stable enaminones with in situ generated diazo reagents from N-tosylhydrazones, followed by selective C-C bond cleavage of the cyclopropane ring affords the 1, 4-ketoaldehyde derivatives in good to excellent yields. This method works with broad substrate scope and high regioseletivity.

  A straightforward strategy for synthesis of highly functionalized trifluoromethyl 2H-furans is described. The copper catalyzed method relies on a cascade cyclic reaction between enaminones and N-tosylhydrazones. This method allows the synthesis of 2-amino-3-trifluoromethyl-substituted 2H-furan derivatives carrying a quaternary stereogenic center as single diastereomers. The proposed reaction mechanism
