5-(6-Hydroxy-2,5,7,8-tetramethylchroman-2-yl)-2-methyl-pentanoic Acid Methyl Ester
A natural diastereomeric mixture of 5-(6-hydroxy-2,5,7,8-tetramethyl-chroman2-yl)-2-methyl-pentanoic acid methyl ester (1), was isolated from the soft coral Sinularia arborea. The structure of 1 was elucidated by spectroscopic methods and 1 displayed a significantly inhibitory effect on the generation of superoxide anion by human neutrophils.
متن کامل5-Iodo-7-methyl-3-methylsulfinyl-2-phenyl-1-benzofuran
The title compound, C(16)H(13)IO(2)S, was prepared by the oxidation of 5-iodo-7-methyl-3-methyl-sulfanyl-2-phenyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 27.17 (9)° with the plane of the benzofuran fragment, with the O atom and the methyl group of the methyl-sulfinyl substituent lying on opposite sides of this plane. The crystal structure exhibi...

In the mol-ecule of the title compound, C(28)H(22)S(2), the two thio-phene rings are twisted with respect to the central benzene ring, making dihedral angles of 71.59 (12) and 50.71 (12)°. The two terminal benzene rings are oriented at dihedral angles of 37.59 (11) and 20.12 (11)° to their bonded thio-phene rings.
متن کامل5-Methyl-2-phenyl-2H-pyrazol-3-ol
The title compound, C(10)H(10)N(2)O, known as Edaravone (MCI-186), was crystallized from methanol. The two independent mol-ecules in the asymmetric unit are linked through an O-H⋯O hydrogen bond. One mol-ecule adopts a ketone form, while the other adopts an enol form. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b...
متن کامل5-Chloro-7-methyl-2-phenyl-3-phenylsulfinyl-1-benzofuran
In the title compound, C(21)H(15)ClO(2)S, the O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane of the benzofuran fragment; the phenyl ring is almost perpendicular to this plane [82.24 (7)°]. The phenyl ring in the 2-position is rotated out of the benzofuran plane, making a dihedral angle of 11.50 (9)°. The crystal structure is stabilized by inter...
