  Synthesis and CYP26A1 inhibitory activity of 1-[benzofuran-2-yl-(4-alkyl/aryl-phenyl)-methyl]-1H-triazoles

  摘要：

  Methodology previously described by our group was applied to the preparation of a series of 4-alkyl/aryl-substituted 1-[benzofuran-2-yl-phenylmethyl]-1H-triazoles. The [1,2,4]-triazole derivatives were prepared for a range of alkyl and aryl substituents, and for the 4-methyl, 4-ethyl, 4-'propyl, 4-'butyl, 4-phenyl and 4-chlorophenyl derivatives, the minor [1,3,4]-triazole isomer also isolated. All the triazole derivatives were evaluated for CYP26A1 inhibitory activity using a MCF-7 cell-based assay. The 4-ethyl and 4-phenyl-1,2,4-triazole derivatives displayed inhibitory activity (IC50 4.5 and 7 mu M, respectively) comparable with that of the CYP26 inhibitor liarozole (IC50 7 mu M). Using a CYP26A1 homology model (based on CYP3A4) template, docking experiments were performed with MOE with multiple hydrophobic interactions observed in addition to coordination between the triazole nitrogen and the haem transition metal.

  strategy for the direct synthesis of 2-aroyl benzofurans from aryne precursors has been developed. This reaction proceeds via C–O and C–C bond cleavage as well as C–O and C–C bond formation in a single reaction vessel. The methodology provides good yields of 2-aroyl benzofurans and tolerates a variety of functional groups. The synthesized 2-aroyl benzofurans were further benzoylated at 3-positions and

  A novel intramolecular oxidative coupling reaction has been established to prepare benzofuran derivatives via direct C(sp²)–H functionalization for the formation of C–O bonds. This transformation is mediated by I₂/TBHP/NaN₃ under metal-free conditions and a catalytic amount of NaN₃ plays a crucial role in the reaction.

  The highly efficient and expedient route for the syntheses of 2-aroyl benzofurans has been developed via the cascade [2+2] followed by a [4+1] annulation on arynes. The overall transformation proceeded through the formation of ortho-quinone methide by the insertion of transient aryne into N,N-dimethylformamide and subsequent trapping with sulfur ylide. Moreover, this transformation has a broad range
