Design, synthesis and anticancer evaluation of novel thiazine, pyrimidine and pyridine derivatives
Journal Title: Iranian Chemical Communication - Year 2017, Vol 5, Issue 2
Abstract
Acylisothiocyanate (1) was allowed to react with benzylidene malononitrile producing oxazine derivative (2). Also, compound (1) was reacted with sodium azide followed by refluxing with sodium ethoxide affording thiazinotetrazole derivative (4). The reaction of acetylacetone with compound (1) gave pyridine derivative (5) by intramolecular cycloaddition while it was reacted with N-methyl aniline affording thiazine derivative (7). In addition, it was reacted with cyanoacetamide producing mercaptopyrimidine derivative (9). Finally, compound (1) was refluxed with phenylhydrazine, urea, guanidinum carbonate and anthranilic acid in the presence of dry acetone affording triazole derivative (11), N-substituted pyrimidine (15), compound (18) and thiopyrimidine derivative (19) respectively. The structures of the new compounds were confirmed on the basis of elemental and spectral data. Some of the synthesized compounds were screened as anticancer.
