Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 2199-44-2, is researched, SMILESS is O=C(C1=C(C)C=C(C)N1)OCC, Molecular C9H13NO2Journal, Journal of Heterocyclic Chemistry called Microwave-accelerated synthesis of benzyl 3,5-dimethyl-pyrrole-2-carboxylate, Author is Regourd, Jasmine; Comeau, Ian M.; Beshara, Cory S.; Thompson, Alison, the main research direction is ethyl pyrrolecarboxylate benzyl alc transesterification microwave irradiation; acetylpyrrolecarboxylate benzyl deacetylation microwave irradiation; pyrrolecarboxylate benzyl preparation.Name: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate.

Benzyl 3,5-dimethyl-pyrrole-2-carboxylate (I), a very useful pyrrole in porphyrin and dipyrromethene synthesis, can be synthesized via the Knorr-type reaction, but in low yield. Alternative routes to I have been developed involving the trans-esterification of Et 3,5-dimethyl-pyrrole-2-carboxylate and the deacetylation of benzyl 4-acetyl-3,5-dimethyl-2-carboxylate, both precursors being easily obtained using the Knorr reaction. These traditional methods involve treatment of the known products with a strong basic solution or heating for extended periods which often lead to decomposition The use of microwave energy to promote these two reactions proves to be an extremely efficient way to obtain I quickly, in high yield, and in excellent purity with no need for recrystallization Of particular note is the use of catalytic sodium methoxide in benzyl alc., rather than stoichiometric amounts of sodium benzoxide, to effect benzylation.

Compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate, is researched, Molecular C9H13NO2, CAS is 2199-44-2, about Nuclear magnetic resonance study of carbethoxypyrroles. Author is Roomi, Mohammad W.; Dugas, H..

The chem. shifts and the ring proton coupling constants of various substituted carbethoxypyrroles are reported. The electron-withdrawing effect of the carbethoxy groups shifts the resonances of the ring substituents to low field while the inductive and mesomeric effects of the Me groups shift the resonances to higher field. The deshielding effect is more pronounced with 2-carbethoxypyrroles than for 3-carbethoxypyrroles. The ring proton spin-spin coupling constants depend on the nature of substituents and increase with the electronegativity of the substituents. In some cases, long-range coupling between the Me side-chain protons and ring protons was observed.
