Direct syntheses of benzofuran-2(3H)-ones and benzofuran-3(2H)-ones from 1-(2-hydroxyphenyl)alkan-1-ones by CuBr2 or CuCl2

New syntheses of benzofuran-2(3H)-ones and benzofuran-3(2H)-ones from 1-(2-hydroxyphenyl)alkan-1-ones via oxidative cyclization by CuBr2 or CuCl2 are described. A new synthesis of 1H-isochromene-1,4(3H)-diones via similar procedures is also described.
