  A new series of flavones, thioflavones, and flavanones as selective monoamine oxidase-B inhibitors

  摘要：

  A new series of synthetic flavones, thioflavones, and flavanones has been synthesized and evaluated as potential inhibitors of monoamine oxidase isoforms (MAO-A and -B). The most active series is the flavanone one with higher selective inhibitory activity against MAO-B. Some of these flavanones (mainly the most effective) have been separated and tested as single enantiomers. In order to investigate the MAOs recognition of the most active and selective compounds, a molecular modeling study has been performed using available Protein Data Bank (PDB) structures as receptor models for docking experiments.

  gram-scale synthesis of flavones is described by a one-pot straightforward sulfoxide-mediated Knoevenagel condensation/intermolecular oxa-Michael annulation/sulfoxide elimination process of β-(o-hydroxyaryl)-ketosulfones (dual nucleophile) and arylaldehydes (dual electrophile). The expeditious synthetic route sets up flavones, including the bond formation of one CO and one double CC bonds via a formal (5 + 1)

  Rh-catalyzed asymmetric hydrogenation of 2-substituted 4H-thiochromenes and 4H-chromenes was successfully developed. This method provided highly efficient access to a series of chiral 2-substituted thiochromanes and chromanes in high yields with excellent enantioselectivities (up to 99% yield, 86–99% ee). The obtained chiral 2-substituted thiochromane products were also successfully transformed to
