Synthesis of Benzo[b]naphtho[2,3-d]thiophene-6,11-diones via Palladium(II) Acetate-mediated Cyclization of 3-Arylthio-1,4-naphthoquinone
摘要:
Palladium(II)-mediated oxidative cyclization of 3-arylthio1,4-naphthoquinone (4) giving biologically important benzo[b]naphtho[2,3-d]thiophene-6,11-diones (2) has been performed with a stoichiometric amount of palladium(II) acetate in distillated acetic acid.
