On December 31, 2007, Shelke, S. N.; Dalvi, N. R.; Gill, C. H.; Karale, B. K. published an article.Synthetic Route of 36640-53-6 The title of the article was Synthesis of various heterocycles from 3-(2-naphthalenyl)-1-phenyl-1H-pyrazole-4-carboxaldehyde. And the article contained the following:
Condensation of the title compound (I) with 2′-hydroxyacetophenones gave propenones II (R1 = H, Cl, Me; R2, R4 = H, Me; R3 = H, Cl, Me, Et, Br, F), which reacted with hydrazine to give pyrazolines III and with iodine in DMSO to give chromones IV. Reaction of IV with hydrazine gave bipyrazoles V. The experimental process involved the reaction of 3-(Naphthalen-2-yl)-1-phenyl-1H-pyrazole-4-carbaldehyde(cas: 36640-53-6).Synthetic Route of 36640-53-6
The Article related to pyrazolecarboxaldehyde condensation hydroxyacetophenone, pyrazolylpyrazoline aryl derivative preparation, pyrazolylchromone aryl derivative preparation, bipyrazole aryl derivative preparation and other aspects.Synthetic Route of 36640-53-6
