4-Bromo-N-methoxy-N-methylbenzamide (cas: 192436-83-2) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Related Products of 192436-83-2

Selective Transformations of Carbonyl Functions in the Presence of α,β-Unsaturated Ketones: Concise Asymmetric Total Synthesis of Decytospolides A and B was written by Yahata, Kenzo;Minami, Masaki;Watanabe, Kei;Fujioka, Hiromichi.

Enones selectively react with a combination of PPh3 and TMSOTf to produce phosphonium silyl enol ethers, which work as protective groups of enones during the reduction of other carbonyl functions and can be easily deprotected to regenerate parent enones at workup. Thus, enone PhCH:CHCOMe reacted with 3-decanone in the presence of PPh3/TMSOTf followed by DIBAL-H reduction and K2CO3/MeOH to give 3-decanol in 96% yield. Treating keto-enones such as 4-MeCOC6H4CH:CHCOMe to the same reaction conditions gave the corresponding selectively reduced product, e.g., 4-MeCH(OH)C6H4CH:CHCOMe in 82% yield. Furthermore, the first ketone selective alkylations in the presence of enones were also accomplished. This in situ protection method was applied to concise asym. total syntheses of decytospolides A and B I (R = H, COMe, resp.). In the experiment, the researchers used many compounds, for example, 4-Bromo-N-methoxy-N-methylbenzamide (cas: 192436-83-2Related Products of 192436-83-2).
