The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3-(Chloromethyl)-1-methyl-1H-pyrazole( cas:84547-64-8 ) is researched.Application In Synthesis of 3-(Chloromethyl)-1-methyl-1H-pyrazole.Bozhenkov, G. V.; Savosik, V. A.; Klyba, L. V.; Zhanchipova, E. R.; Mirskova, A. N.; Levkovskaya, G. G. published the article 《1-Alkylpyrazoles and 1-alkyl-5-chloropyrazoles from halovinyl ketones and 1,1-dialkylhydrazines》 about this compound( cas:84547-64-8 ) in Russian Journal of Organic Chemistry. Keywords: ketone chloro vinyl heterocyclization hydrazine dialkyl; pyrazole alkyl chloro preparation. Let’s learn more about this compound (cas:84547-64-8).
Regioselective heterocyclization of chlorovinyl ketones R1COCH:C(R2)Cl (R1 = Me, R2 = H; R1 = n-Pr, R2 = H, Cl; R1 = CH2Cl, R2 = H) with 1,1-dialkyl-hydrazines NH2N(R3)2 (R3 = Me, n-Bu) to pyrazoles I involved intermediate formation of the corresponding dialkylhydrazones II. The mass spectrum fragmentation pattern of chlorine-containing pyrazoles I (R1 = CH2Cl, R2 = H, R3 = Me; R1 = n-Pr, R2 = Cl, R3 = Me) depended on the position of the halogen atom.
As far as I know, this compound(84547-64-8)Application In Synthesis of 3-(Chloromethyl)-1-methyl-1H-pyrazole can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
