چکیده
In the title compound (5HIN), C(9)H(8)O(2), is perfectly planar as all atoms, except the H atoms of both CH(2) groups, lie on a crystallographic mirror plane. In the crystal, mol-ecules are linked by strong inter-molecular O-H⋯O hydrogen bonds, forming an infinite chain along [100], generating a C(8) motif.

In the title compound, C(9)H(8)O(2), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The dihedral angle between the mean plane of the S(6) ring and the benzene ring is 1.89 (2)°. In the crystal, inversion-related mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming a cyclic dimers with R(2) (2)(12) graph-set motif. Weak inter-molecular C-H⋯O(carbon-yl) and C-H⋯O(hy-dro...
متن کامل5-Benzamidoisoquinolin-1-ones and 5-(ω-carboxyalkyl)isoquinolin-1-ones as isoform-selective inhibitors of poly(ADP-ribose) polymerase 2 (PARP-2).
PARP-2 is a member of the poly(ADP-ribose) polymerase family, with some activities similar to those of PARP-1 but with other distinct roles. Two series of isoquinolin-1-ones were designed, synthesized, and evaluated as selective inhibitors of PARP-2, using the structures of the catalytic sites of the isoforms. A new efficient synthesis of 5-aminoisoquinolin-1-one was developed, and acylation wi...

Four types of N-heterocyclic ring systems were successfully constructed from the reactions of 1-alkynyl Fischer carbene complexes (OC)5M=C(OEt)C[triple bond]CPh (1) (M = Cr, W) and substituted pyrazolinones (2). Reactions of 1 with 3-methyl-2-pyrazolin-5-one (2a), 3-n-propyl-2-pyrazolin-5-one (2b), 3,4-dimethyl-2-pyrazolin-5-one (2c), 3,4-trimethylene-2-pyrazolin-5-one (2d), or 3,4-tetramethyle...
