  New domino reaction. One pot synthesis of 4,7-dihydroxythioaurone derivatives from benzaldehydes and 4-acetyl-2-oxo-benz[1,3]oxathiole

  摘要：

  A convenient synthesis of 4,7-dihydroxythioaurone derivatives by a one pot reaction of benzaldehydes with 4-acetyl-2-oxobenz[1,3]oxathioles and piperidine acetate in DMSO is described. The structures of the compounds, including double bond geometry were proved unequivocally by NMR methods. The thioaurone ring system seems to be formed by three consecutive reactions: opening of the oxathiolone ring with piperidine, oxidation of the formed mercapto group with DMSO or/and air to disulfide, and condensation with aldehyde.

  Isomeric, oxathiolone fused chalcones bearing 0-aminoalkyl side chain were synthesized by condensation of suitable benzoxathiolones with substituted benzaldehydes. The starting benzoxathiolones were prepared by O-alkylation of corresponding phenols with aminoalkyl chlorides, however, the reaction was often complicated by amino group catalyzed opening of the oxathiolone ring. The obtained chalcones were screened for antimicrobial and cytotoxic activity.
