Hydrogen bonding in nitroaniline analogues: a hydrogen-bonded chain of rings in 2-amino-4-butylamino-6-methoxy-5-nitropyrimidine.
In the title compound, C(9)H(15)N(5)O(3), in which the molecules exhibit orientational disorder, the molecules of the major component are linked by paired N-H...O hydrogen bonds [H...O = 2.37 and 2.39 A, N...O = 2.974 (3) and 3.011 (3) A, and N-H...O = 126 and 128 degrees ] to form a C(8)C(8)[R(2)(2)(6)] chain of rings along [010]. The minor component (6.5% of the molecules) forms a similar cha...
متن کاملSYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
متن کامل4-Bromoanilinium hydrogen phthalate
In the anion of the title compound, C(6)H(7)BrN(+)·C(8)H(5)O(4) (-), the dihedral angles formed by the benzene ring and the mean planes of the -COOH and -COO(-) groups are 20.6 (3) and 83.2 (3)°, respectively. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect the cations and anions, forming a two-dimensional network parallel to (001).

متن کاملCrystal structures of 4-methoxy-6-methyl- and 4-hydroxy-6-methyl-2-pyrones.
interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
