Pyrido[2,3-d]pyrimidines. II. Synthesis of ribonucleosides of 4-oxo- and 2,4-dioxopyrido[2,3-d]pyrimidines was written by Rizkalla, Boshra H.;Broom, Arthur D.;Stout, Mason G.;Robins, Roland K.. And the article was included in Journal of Organic Chemistry in 1972.Recommanded Product: 14667-47-1 This article mentions the following:
Synthesis of 1-β-D-ribofuranosyl-4-oxopyrido[2,3-d]pyrimidine and 1- and 8-β-D-ribofuranosyl-2,4-dioxopyrido[2,3-d]pyrimidine are described. The site of ribosylation in each case is assigned by uv and PMR comparisons with requisite N-Me model compounds The assignment of anomeric configuration is based upon PMR spectroscopy. A facile N-8 â?N-1 ribosyl rearrangement is described. In the experiment, the researchers used many compounds, for example, Methyl 2-aminonicotinate (cas: 14667-47-1Recommanded Product: 14667-47-1).
Methyl 2-aminonicotinate (cas: 14667-47-1) 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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Recommanded Product: 14667-47-1
