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...

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 ...

In the title compound, C25H18BClF2N2OS, the characteristic B-N and B-O bond lengths are 1.571 (3) and 1.458 (3) Å, respectively. The phenyl rings form dihedral angles of 83.1 (1) and 64.6 (1)° with the chloro-phenyl ring. In the crystal, weak C-H⋯N, C-H⋯F, C-H⋯π and π-π inter-actions [centroid-centroid distances 3.877 (6) Å between the chloro-phenyl rings of neighbouring mol-ecules] held mol-ec...

متن کاملESI-MS spectra of 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones
Twelve 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones were investigated by tandem mass spectrometry using positive as well as negative electrospray ionization. The influence of the electron affinity of the substituent and the steric effect on the fragmentation is discussed. Pyridinones with a substituent of low proton affinity show loss of water, HCN or benzene from the pyridinone ri...
