Organic compounds having carbon bonded to bromine are called organic bromides. 5392-10-9, formula is C9H9BrO3, Name is 2-Bromo-4,5-dimethoxybenzaldehyde. Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Category: bromides-buliding-blocks.
Phumjan, Tanawat;Songthammawat, Poramate;Jongcharoenkamol, Jira;Batsomboon, Paratchata;Ruchirawat, Somsak;Ploypradith, Poonsakdi research published 《 Substituted 9-Anthraldehydes from Dibenzocycloheptanol Epoxides via Acid-Catalyzed Epoxide Opening/Semipinacol Rearrangement》, the research content is summarized as follows. Starting from benzaldehyde derivatives, the corresponding dibenzocycloheptenol could be prepared in five steps. Under both substrate (secondary vs tertiary alc. and the substituents on the aromatic ring(s)) and condition control, the subsequent epoxidation and acid-catalyzed epoxide opening/semipinacol rearrangement/aromatization afforded the corresponding 9-anthraldehydes in good yields, up to 88% over two steps. The presence of the electron-withdrawing group(s) on the aromatic ring(s) suppressed the rate of the epoxidation while the subsequent semipinacol rearrangement step required heating; the presence of the electron-donating group(s), on the other hand, frequently led to the decomposition during the epoxidation From the mechanistic studies, the semipinacol rearrangement of the epoxide could precede the ionization at the bisbenzylic position, yielding the aldehyde intermediate. The ensuing dehydrative aromatization led to the formation of 9-anthraldehyde. Conversely, nucleophilic addition to the aldehyde and dehydrative aromatization with concomitant loss of formic acid led to anthracene.
Category: bromides-buliding-blocks, 2-Bromo-4,5-dimethoxybenzaldehyde is a useful research compound. Its molecular formula is C9H9BrO3 and its molecular weight is 245.07 g/mol. The purity is usually 95%.
2-Bromo-4,5-dimethoxybenzaldehyde is a synthetic compound that has been shown to be an effective agent for inducing apoptosis in leukemia cells. It is an efficient method for synthesizing the compound and ha2-Bromo-4,5-dimethoxybenzaldehyde induces cell death by topoisomerase-mediated DNA cleavage, which results in chromosomal fragmentation and high levels of reactive oxygen species in the cell., 5392-10-9.
