Synthesis of 2-[(Z)-1-hydropolyfluoro-1-alkenyl]-4H-3,1-benzoxazin-4-ones
Liu,Lue
, p. 213 - 216 (2007/10/03)
N,N′-dicyclohexylcarbodiimide induced condensation of 2,2-dihydropolyfluoroalkanoic acid and anthranilic acid or its derivatives followed by a dehydrating ring-closure reaction in the presence of Ac2O gave 2-[(Z)-1-hydropolyfluoro-1-alkenyl]-4H-3,1-benzoxazin-4-ones in good to excellent yields.
