Synthesis of indoles and quinolones by sequential Wittig and Heck reactions

Abstract
Trifluoroacetamido derivatives 18a–c and 19a–c react with phosphorane 2 in boiling toluene to give the corresponding enamines 12a–c and 13a–c respectively which are precursors of the trifluoromethylated indoles 14a–c and quinolones 15a–c.
