| Abstract: | A new method was found for the synthesis of pyrazoleacetate esters from pyrazolaldehyde.By a new tandem reaction. in which methyl 4-pyrazoleacetate reacted with carbon disulfide andiodomethane. thieno2.3-c]pyrazole was synthesized. This was an easy method for the synthesis ofthis type of heterocyeles. |
