1-Methyl-1H-indazole-3-carboxylic acid
The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.
متن کاملSynthesis, Reactions and Antioxidant Activity of 5-(3', 4'-dihydroxy-tetrahydrofuran-2'-yl)-2-methyl-3-carbohydrazide
In this manuscript, we describe the synthesis of the carbohydrazide 2. Acid-catalyzed condensation with several carbonyl compounds to afford the corresponding carbohydrazide derivatives 3-12. Their acetylation afforded the corresponding acetyl derivatives 13-22. Oxidative cyclization of O-acetyl derivatives 19-22 afforded the corresponding 1,3,4-oxadiazole derivatives 23-2...
متن کامل3-Methyl-N-phenylbenzamide
The conformation of the C=O bond in the structure of the title compound, C(14)H(13)NO, is anti to the meta-methyl substituent in the benzoyl ring. The conformations of the N-H and C=O bonds in the amide group are also anti to each other. The asymmetric unit of the structure contains two mol-ecules. The bond parameters are similar to those in N-(phen-yl)benzamide, 2-methyl-N-(phenyl)-benz-amide ...
متن کاملCoordination compounds based on 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid.
Syntheses of 2,6-bis[((3S)-3-(methoxycarbonyl)-1,2,3,4-tetrahydroisoquinolin-2-yl)carbonyl]pyridine and its coordination compounds with Cu2+, Co2+, Co3+, or Fe3+ are described. By means of 1H- and 13C-NMR spectra it was proved that 2,6-bis[((3S)-3-(methoxycarbonyl)-1,2,3,4-tetrahydroisoquinolin-2-yl)carbonyl]pyridine as well as its coordination compound with Co3+ exist in the form of a mixture ...

dl-[/?-14C] 3,4-Dihydroxyphenylalanine (DOPA), [2-14C]pyruvate and [2-14C]acetate were ad ministered to a callus culture of S. hassjoo and incorporation of the radioactivity into 3-carboxy6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline (I) and l-methyl-3-carboxy-6,7-dihydroxy-1,2,3,4tetrahydroisoquinoline (II) was examined. Incorporation of radioactivity from labelled DOPA into I and II, and from...
