چکیده
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 pseudo-Michael reaction of 1-aryl-4,5-dihydro-1H-imidazol-2-amines with ethyl ethoxymethylenecyanoacetate
ABSTRACT The pseudo-Michael reaction of 1-aryl-4,5-dihydro-1H-imidazol-2-amines with ethyl 2-cyano-3-methoxyprop-2-enoate (ethyl ethoxymethylenecyanoacetate) is investigated. At -10 °C reaction takes place on the exocyclic nitrogen atom, giving exclusively ethyl esters of 2-cyano-3-[(1-phenyl-4,5-dihydro-1H-imidazol-2-yl)amino]prop-2-enoic acid. The formation of isomeric enamines which may be a...

In the title compound, C(25)H(26)N(4)O(3), the two fused pyrrolo-[3,2-d]pyrimidine rings form a dihedral angle of 3.7 (2)°. The two substituent phenyl rings are twisted with respect to the pyrrole and pyrimidine rings, making dihedral angles of 57.2 (2) and 69.0 (2)°, respectively. The ethyl and eth-oxy groups are disordered over two positions; the site occupancies are 0.53 (1) and 0.47 (1) for...
