l-2-Nitrimino-1,3-diazepane-4-carboxylic acid monohydrate
The cyclic form of l-nitro-arginine, C(6)H(10)N(4)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. According to the geometrical parameters, similar in both mol-ecules, the structure corresponds to that of l-2-nitrimino-1,3-diazepane-4-carboxylic acid; there are, however, conformational differences between the independent molecules, one of them being close to a twisted ...
متن کامل2-(Carboxymethylsulfanyl)pyridine-3-carboxylic acid monohydrate
The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°. The carboxy-methyl-sulfanyl group makes a torsion angle of 82.64 (12)° with the pyridine ring. An intra-molecular ...
متن کاملSynthesis and biological properties of Enantiomers of 1-Allyl-4-Hydroxy-6,7-Dimethoxy-2-Oxo-1,2- Dihydroquinoline-3-Carboxylic Acid (1-Ethylpyrrolidin- 2-Ylmethyl)-Amide Hydrochloride
Being guided by the methodological principles of "chiral switches", the synthesis of Sand Renantiomers of 1-allyl-4-hydroxy-6,7-dimethoxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acid (1ethylpyrrolidin-2-ylmethyl)-amide hydrochloride has been carried out. According to the results of the biological research, it has been found that the ability of the optical isomers obtained to block opioid recept...
متن کامل2-Methyl-4-oxo-6,7,8,9-tetrahydrothieno[2′,3′:4,5]pyrimidino[1,2-a]pyridine-3-carboxylic acid
There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)N(2)O(3)S. With the exception of the methyl-ene groups, a mean plane fitted through all non-H atoms of each mol-ecule has an r.m.s. deviation of 0.035 Å for one mol-ecule and 0.120 Å for the second. In one of the independent mol-ecules, the methyl-ene groups was refined using a disorder model with an oc...
متن کامل1,2-Dihydroxy-2-(3-methylbut-2-enyl)-3-oxo-2,3-dihydro-1H-indene-1-carboxylic acid monohydrate
The title compound, C(15)H(16)O(5)·H(2)O, is an inter-mediate of the Hooker oxidation reaction, used for the synthesis of 2-hydr-oxy-3-(2-methyl-prop-1-en-yl)naphthalene-1,4-dione (nor-lapachol). The packing in the crystal structure is arranged by an O-H⋯O hydrogen-bonded network along the [100] and [010] directions. Each organic mol-ecule is linked to four other mol-ecules via the hydr-oxy gro...
