title: CeCl₃.7H2O/NaI-promoted direct synthesis of 1,3-benzoxazine-2-thione n-nucleosides under microwave irradiation.
abstract: A microwave-assisted efficient and direct synthetic route to 1,3-benzoxazine-2-thione N-nucleos ides via CeCl₃.7H2O/NaI catalyzed cycloisomerization of salicylaldehyde 4-(β-D-ribofuranosyl) thiosemicarbazones followed by reductive dehydrazination is reported.
