4-Methoxyquinolinium-2-carboxylate dihydrate
The title hydrated quinoline derivative, C(11)H(9)NO(3)·2H(2)O, crystallizes as a zwitterion in which the quinoline N atom is protonated. The quinoline ring is essentially planar, with a maximum deviation of 0.017 (2) Å. An intra-molecular N-H⋯O hydrogen bond between the protonated N atom and the O atom of the carboxyl-ate group in the zwitterion forms an S(5) ring motif. In the crystal, the zw...

The crystal structure of the title salt, C(5)H(7)N(2) (+)·C(8)H(7)O(2) (-)·2H(2)O, contains a three-dimensional supra-molecular framework constructed through N-H⋯O and O-H⋯O hydrogen bonds.
متن کامل4-Amino-2-methylquinolinium hydrogensulfate dihydrate
In the title compound, C(10)H(11)N(2) (+)·HSO(4) (-)·2H(2)O, the asymmetric unit contains two protonated 4-amino-quinoline cations and two hydrogen sulfate anions with four water mol-ecules. The crystal structure involves extensive N-H⋯O and O-H⋯O hydrogen bonding.
متن کاملEthyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole- 2-carboxylate
This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine and a nitrile oxide functionality. The latter reacts with an immobilized thiourea to yield an isothiocyanate which upon elimination generates ...

BACKGROUND Pyrimethamine [2,4-diamino-5-(p-chlorophenyl)-6-ethylpyrimidine] is an antifolate drug used in anti-malarial chemotherapy. Pyrimidine and aminopyrimidine derivatives are biologically important compounds owing to their natural occurrence as components of nucleic acids. RESULTS In the crystal structures of two organic salts, namely pyrimethaminium benzenesulfonate monohydrate 1 and 2...
