Synthesis, antimicrobial and antiviral evaluation of certain thienopyrimidine derivatives
摘要:
A series of 2-substituted amino-3-aminocyclopenteno or cyclohexeno[b]thieno[2,3-d]-3,4-dihydropyrimidin-4-ones has been synthesized by reacting the corresponding thioureido derivatives with hydrazine hydrate. The thienoprimidine analogues obtained were further used to prepare their arylideneamino, thienotriazolopyrimidine or 2-methylthienotriazolopyrimidine derivatives. The prepared compounds were screened for antimicrobial, antiviral and cytotoxic activity. Some of the tested compounds showed promising activity. Detailed syntheses and spectroscopic and biological data are reported.

The title compounds substituted 2‐lactosylthiothieno[2,3‐d]pyrimidin‐4‐ones 6 were synthesized by the glycosyl reaction and alcoholysis reaction of substituted 2‐thioxo‐thieno[2,3‐d]pyrimidin‐4‐ones 4,which is formed by the base catalytic and acetic acidify reaction of amino esters 2 with alkyl or arylisothiocyanates and hepta‐O‐acetyl‐lactosyl bromide in good yields. All of the compounds were confirmed by NMR, ESI‐MS, and elemental analysis.
