Fe-promoted oxidative cyclization of α-benzoylthioformanilides for the synthesis of 2-benzoylbenzothiazoles†
Abstract
2-Benzoylbenzothiazoles were obtained in good yields via an efficient synthesis involving oxidative cyclization of α-benzoylthioformanilides catalyzed by FeCl3. This protocol has the advantages of short reaction times, moderate to good yields, convenient manipulation, and high selectivities.
