An Expeditious Synthesis of New 5-acetyl-4-(4’-alkyloxyphenyl)- 3-cyano-6-methylpyridine-2(1H)-thiones and Derivatives
A convergent synthesis of 5-acetyl-4-(4'-alkyloxyphenyl)-3-cyano-6-methylpyridine-2(1H)-thiones and their derivatives S-alkylthiopyridines was described. The main steps towards the formation of the title compounds involve the reactions of 4-alkyloxybenzaldehydes with 2-cyanothioacetamide to afford 2-cyano-3(4'-alkyloxyphenyl)prop-2-enethioamides which then reacted with acetylacetone prior to th...
متن کاملTriphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans
Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...
متن کامل(4-Chlorobenzoyl)(4-chlorophenyl)amino 3-(2-nitrophenyl)propanoate
In the title hydroxamic acid derivate, C22H16Cl2N2O5, the nitro-substituted benzene ring forms dihedral angles of 14.11 (15) and 16.08 (15)°, with the 4-chloro-benzoyl and 4-chloro-phenyl benzene rings, respectively. The dihedral angle between the chloro-substituted benzene rings is 2.28 (13)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along [100].

In the title compound, C(16)H(16)N(2)O(3)S·C(5)H(5)N, the benzene and thia-zole rings of the Febuxostat [2-(3-cyano-4-isobut-yloxy)phenyl-4-methyl-5-thia-zolecarboxylic acid] mol-ecule are almost coplanar [dihedral angle = 2.4 (1)°]. The carboxyl group is coplanar with the thia-zole ring [O-C-C-C and O-C-C-S torsion angles of -0.7 (4) and 0.6 (3)°, respectively]. The pyridine mol-ecule of cryst...
