  Synthesis of Substituted Alkoxythiophenes: Thiophene Analogues of Dazoxiben

  摘要：

  The synthesis of the thiophene analogue of dazoxiben - one of the most selective TXA(2)-synthase inhibitors - and its derivatization to a chlorinated, more lipophilic product is described. The ethylenoxy moiety was introduced via nucleophilic aromatic substitution of halogenated thiophene carboxylic esters, the imidazol residue, by use of a t-butoxy group as a synthon after ether cleavage and halogenation. Also, at this step chlorination of the thiophene moiety was carried out. After ester hydrolysis the target compounds were obtained as hydrochlorides.
