Name: Ethyl 2-methyl-3-oxobutanoateIn 2021 ,《Calcium-Catalyzed Intramolecular Hydroamination-Deacylation Reaction of in situ formed β-Amino Allenes》 appeared in Advanced Synthesis & Catalysis. The author of the article were Yaragorla, Srinivasarao; Latha, Dandugula Sneha; Rajesh, Pallava. The article conveys some information:
A simple, one-Pot, three-component reaction of tert-propargyl alcs., primary amines and acyl ketones to synthesize fully substituted pyrroles and pyridine derivatives in good to excellent yields with large substrate diversity was developed. An eco-friendly calcium catalyst catalyzed the reaction to form the key intermediate β-amino allene that undergoes subsequent Thorpe-Ingold effect assisted hydroamination and aromaticity driven deacylation reaction to yield fully substituted five and six-membered azacyclic compounds In the part of experimental materials, we found many familiar compounds, such as Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3Name: Ethyl 2-methyl-3-oxobutanoate)
Ethyl 2-methyl-3-oxobutanoate(cas: 609-14-3) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Name: Ethyl 2-methyl-3-oxobutanoate
