Ethyl 3-methyl-4-oxo-4,5-dihydro-1H-pyrrolo[2,3-d]pyridazine-2-carboxylate
The title compound, C(10)H(11)N(3)O(3), was synthesized by the reaction of 3,5-bis-(ethoxy-carbon-yl)-2-formyl-4-methyl-1H-pyrrole and hydrazine hydrate. The angle between the pyrrole ring and the pyridazinone ring is 0.93 (9)°. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen-bond inter-actions link the mol-ecules into a two-dimensional network.

The synthesis of 6- methyl- 2- phenyl- 7H- oxazolo [3,2-b] 1,2,4-Triazine- 7-one (6, R=Ph) and its 2-P- bromophenyl analogue to the two members of a new heterocyclic system is described
متن کامل3-Chloro-6-[4-(2-pyridyl)piperazin-1-yl]pyridazine
In the title compound, C(13)H(14)ClN(5), the piperazine ring adopts a chair conformation and the dihedral angle between the aromatic rings is 13.91 (7)°. The crystal structure is stabilized by weak inter-molecular C-H⋯N hydrogen-bond inter-actions.
متن کاملSynthesis of methyl 2-[2-(alkylimino)-4-oxo-3-phenyl-1,3-thiazolan-5-yliden]acetate derivatives under solvent-free condition
An efficient synthesis of Methyl 2-[2-(alkylimino)-4-oxo-3-phenyl-1,3-thiazolan-5-yliden]acetate derivatives via simple three-component reaction and one-pot reactions between isoquinoline, dimethyl acetylenedicarboxylate and N-phenylthiourea under solvent-free conditions without using any additional catalyst, is described. The mild reaction conditions and good yields and exhibit the synthetic a...
متن کامل3-Chloro-6-[2-(propan-2-ylidene)hydrazinyl]pyridazine
In the title compound, C(7)H(9)ClN(4), the 3-chloro-6-hydrazinylpyridazine unit is planar (r.m.s. deviation = 0.0219 Å) and is oriented at a dihedral angle 4.66 (27)° with respect to the propan-2-yl-idene group. In the crystal, the mol-ecules are linked into non-planar dimers due to a crystallographic twofold rotation via N-H⋯N hydrogen bonds with R(2) (2)(8) graph-set ring motifs.
