Study of [1,3] sigmatropic hydrogen migration in
thymine, thymidine and thymidylic acid by AM1 method |
The
geometry and electronic structures of thymine, thymidine and thymidylic acid
involving [1,3] sigmatropic hydrogen migration in the formation of tautomers
have been fully optimized and evaluated by semi-empirical molecular orbital
AM1 method. Thermodynamic parameters and mechanistic aspects have been
investigated and are discussed. |

Chalcones, pyrazolines and
aminopyrimidines as antibacterial agents |
2,4–Bis-ethylamino-6-[4'-{3"-(substitutedphenyl/2'"-furanyl)-2"-propenon
-1"-yl} phenyl amino]-s-triazine
5a-d have been prepared by
treating ketone 4 with different
substituted aromatic and heterocyclic aldehydes in the presence of alkali.
These chalcones 5a-d on
cyclisation with hydrazine hydrate and guanidine nitrate to form pyrazolines 6a-d and aminopyrimidines 7a-d respectively. The structures of
the synthesized compounds have been
established on the bases of IR, 1H NMR and elemental
analysis. The
compounds have been evaluated for antibacterial activity against E. coli, |
