Ethyl 2-(3-chloro-2-pyridyl)-5-oxopyrazolidine-3-carboxylate
In the mol-ecule of the title compound, C(11)H(12)ClN(3)O(3), the five membered ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
متن کاملEthyl 1-(2-bromopropanoyl)-4-hydroxy-2,6-diphenyl-1,2,5,6-tetrahydropyridine-3-carboxylate
The title compound, C(23)H(24)BrNO(4), crystallizes with two independent mol-ecules per asymmetric unit. The methyl group of the ethoxy-carbonyl unit is disordered over two positions, with occupancies of 0.715 (12) and 0.285 (12) in one of the independent mol-ecules, and 0.529 (11) and 0.471 (11) in the other mol-ecule. In one of the independent mol-ecules, the tetra-hydro-pyridine ring adopts ...
متن کاملCrystal structure of ethyl 2-(4-chlorophenyl)-3-cyclopentyl-4-oxo-1-propylimidazolidine-5-carboxylate
The title compound, C20H27ClN2O3, was obtained via an original synthesis method. The central heterocyclic ring adopts a shallow envelope conformation, with the N atom bearing the cyclo-pentane ring as the flap [deviation from the other atoms = 0.442 (2) Å]. The cyclo-pentane ring adopts a twisted conformation about one of the CN-C bonds: the exocyclic C-N bond adopts an equatorial orientation. ...
متن کاملEthyl 6-r-(2-chlorophenyl)-2-oxo-4-phenylcyclohex-3-ene-1-t-carboxylate
In the title mol-ecule, C(21)H(19)ClO(3), the cyclo-hexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 12.75 (14) and 74.16 (8)° with the phenyl and benzene rings, respectively. The dihedral angle between the latter two rings is 81.73 (12)°. Inter-molecular C-H⋯O hydrogen bonds and intra-molecular C-H...
متن کامل3-Ethyl-2-(ethylimino)-4-methyl-2,3-dihydro-1,3-thiazole-5-carboxylate Ethyl Ester
An efficient procedure to obtain the new compound 1a from ethyl acetoacetate (2a), NBS and N,N′-diethylthiourea (4a) was reported. In comparison with the traditional method to synthesize its analogues, this efficient, catalyst-free, and one-pot synthetic method is facile. The work-up procedure is easy and gives the pure target compound under milder reaction conditions in a relatively high yield...
