A Convenient Synthesis of 3(2)-Trifluoroacetylaminobenzo[b]thiophenes and Thiophenes and Some of Their Iodo Derivatives
摘要:
Trifluoroacetylamino derivatives of benzo[b]thiophene and thiophene (3a-d) have been obtained by Curtius rearrangement of the corresponding acyl azides (1a-d) with trifluoroacetic acid. The iodination of these amide derivatives with iodine under mild conditions leads to iodinated products in excellent yield, except in the case of the 3-trifluoroacetylaminobenzo[b]thiophene (3a), which only gives a polymeric residue.
