The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3-Methyl-1H-pyrrole( cas:616-43-3 ) is researched.Category: chiral-oxygen-ligands.Groves, J. K.; Anderson, Hugh J.; Nagy, H. published the article 《Pyrrole chemistry. XIII. New syntheses of 3-alkylpyrroles》 about this compound( cas:616-43-3 ) in Canadian Journal of Chemistry. Keywords: pyrrole alkyl preparation. Let’s learn more about this compound (cas:616-43-3).
3-n-Alkylpyrroles are prepared in good yield by a combined Wolff-Kishner reduction and hydrolysis and decarboxylation of 4-acyl-2-pyrrole-thiolcarboxylates. Me 4-isopropyl-2-pyrrolecarboxylate and 4-tert-butyl-2-pyrrolecarbonitrile are prepared by alkylation of Me 2-pyrrolecarboxylate and 2-pyrrolecarbonitrile, resp. Hydrolysis and decarboxylation of these disubstituted compounds afford the corresponding-3-alkylpyrroles. Mass spectral data for some 1-, 2-, and 3-alkylpyrroles are reported.
