5-Unsubstituted 2-pyrrolecarboxaldehydes for porphyrin synthesis and the cyanovinyl protecting group was written by Paine, John B. III;Dolphin, David. And the article was included in Journal of Organic Chemistry in 1988.Recommanded Product: 2199-49-7 This article mentions the following:
(Cyanovinyl)pyrroles I (R = Me, R1 = Et, octyl; R = Et, R1 = Me) derived from the Knoevenagel condensation of benzyl 5-formyl-2-pyrrolecarboxylates with NCCH2CO2Me were employed in a facile sequence of 4 steps to produce, regioselectively, 2-pyrrolecarboxaldehydes II, important intermediates for porphyrin synthesis. Each step proceeded in 90-95% yield, making II available smoothly from benzyl 5-methyl-2-pyrrolecarboxylates in 7 steps, with an overall yield of 66-72%. In the experiment, the researchers used many compounds, for example, Ethyl 4-methyl-1H-pyrrole-3-carboxylate (cas: 2199-49-7Recommanded Product: 2199-49-7).
Ethyl 4-methyl-1H-pyrrole-3-carboxylate (cas: 2199-49-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 2199-49-7
