3-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...
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 ...
متن کاملEthyl 1-[(2-chloro-1,3-thiazol-5-yl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylate
In the title compound, C(10)H(11)ClN(4)O(2)S, the triazole ring carries methyl and ethoxy-carbonyl groups and is bound via a methyl-ene bridge to a chloro-thia-zole unit. There is also evidence for significant electron delocalization in the triazolyl system. Intra- and inter-molecular C-H⋯O hydrogen bonds together with strong π-π stacking inter-actions [centroid-centroid distance 3.620 (1) Å] s...
متن کامل2-Ethyl 4-methyl 5-ethyl-3-methyl-1H-pyrrole-2,4-dicarboxylate
The title pyrrole derivative compound, C(12)H(17)NO(4), was synthesized from methyl 3-oxopenta-noate by a Knorr-type reaction and contains a pyrrole ring to which two diagonal alk-oxy-carbonyl groups and two diagonal alkyl substituents are attached. The methyl-carbonyl and ethyl-carbonyl substituents are approximately co-planar with the pyrrole ring, making dihedral angles of 5.64 (2) and 3.44 ...
متن کاملEthyl 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.
