Organobromine compounds, also called organobromides, are organic compounds that contain carbon bonded to bromine. 70-23-5, formula is C5H7BrO3, The most pervasive is the naturally produced bromomethane. Formula: C5H7BrO3
Yakovenko, Georgiy G.;Lukianov, Oleh A.;Yagodkina-Yakovenko, Marta S.;Bol’but, Andriy V.;Vovk, Mikhailo V. research published 《 Synthesis of 5-amino-1H-pyrazolo[4,3-b]pyridine derivatives and annulation of imidazole and pyrimidine rings thereto》, the research content is summarized as follows. A series of 5-amino-1H-pyrazolo[4,3-b]pyridine derivatives I [R1 = Me, Et, Ph, etc.; R2 = H, OMe; R3 = CN, C(O)NH2, CO2tBu] was synthesized via Friedlander reaction of N-Boc-protected 1-alkyl(aryl)-5-formyl-1Hpyrazol-4-amines with alkyl nitriles. Cyclocondensation of some of the compounds I with orthoesters, Et oxalyl chloride or carbonyldiimidazole to afford pyrazolo[3′,4′,5,6]pyrido[2,3-d]pyrimidine derivatives II [R4 = Me, tBu, Ph; R5 = H, iPr, Ph] and III [R1 = Me, Et, Ph, etc.] was reported. Cyclocondensation of some of the compounds I with chloroacetaldehyde, bromotrifluoroacetone or Et bromopyruvate to form imidazo[1,2-a]pyrazolo[3,4-e]pyridines IV [R6 = Me, Et, tBu, Ph; R2 = H, OMe; R7 = CN, C(O)NH2; R8 = H, CO2Et, CF3] was reported.
70-23-5, Ethyl bromopyruvate molecular formula is C5H7BrO3 and its molecular weight is 195.01 g/mol. The purity is usually 95%.
Ethyl bromopyruvate is used in a synthesis of thioxothiazolidines from carbon disulfide and primary amines.
Ethyl bromopyruvate is a chemical inhibitor that inhibits the enzyme pyruvate dehydrogenase, which is responsible for the conversion of pyruvic acid to acetyl-CoA. This inhibition leads to a decrease in ATP levels and can cause metabolic disorders. Ethyl bromopyruvate is used as an anthelmintic drug and in asymmetric synthesis. It is also used in the synthesis of thiostrepton, an antibiotic that has been shown to have antimicrobial activity against Gram-positive bacteria, including Staphylococcus aureus and Streptococcus pneumoniae., Formula: C5H7BrO3
