چکیده
In the title compound, C(16)H(12)BrNO, the ring systems subtend an inter-planar dihedral angle of 75.95 (3)°. In the crystal packing, mol-ecules are linked to form centrosymmetric pairs by pairs of classical N-H⋯O hydrogen bonds.

A simple access to N-(un)substituted isoquinolin-1(2H)-ones: unusual formation of regioisomeric isoquinolin-1(4H)-ones.
A ligand/additive/Pd-free Cu-mediated coupling/cyclization strategy afforded the first practical, one-pot and general approach towards synthesis of N-(un)substituted isoquinolin-1(2H)-ones. Both the catalyst and the solvent used are recyclable. The use of the Cu reagent in excess led to the unusual formation of regioisomeric and uncommon isoquinolin-1(4H)-ones.

متن کاملA straightforward synthesis of indazolo[3,2-a]isoquinolin-6-amines
4-Substituted 1-bromoisoquinolin-3-amines were subjected to Suzuki coupling with o-nitrophenylboronic acid to yield 1-(2-nitrophenyl)isoquinolinamines, which participated in Cadogan cyclization with triethyl phosphite under microwave irradiation and pressure to yield fluorescent indazolo[3,2-a]isoquinolin-6-amines. The new compounds were also functionalized by transformation of the amino group.
