  Synthesis and antimicrobial activity of some 2-alkyl-2H-1,4-benzothiazin-3(4H)-ones and 2-alkylbenzo[d]imidazolo[2,1-b]-thiazolidin-3-ones

  摘要：

  Sodium 2-aminothiophenoxide (1) reacts with ethyl 2-bromoalkanoates (2) under direct cyclization to form 2-alkyl-2H-1,4-benzothiazin-3(4H)-ones (3). Reaction of the sodium salt of 2-mercaptobenzimidazole (4) with 2 or 2-bromoalkanoic acids (5) affords only S-alkylated products (6 or 7, respectively). The cyclization products - 2-alkylbenzo[d] imidazolo[2,1-b]thiazolidin-3-ones (8)- can be obtained only from the corresponding 2-(2-benzimidazolylthio)alkanoic acids (7) by the action of acetic anhydride. Both compounds 3 and 8 exhibit only moderate antimicrobial activity against some gram-positive bacteria.
