A facile and efficient Rh(III)-catalyzed annulation of arylamides with 3-diazoquinolinediones for the construction of diverse and highly functionalized isochromenoquinolinediones was described. Furthermore, the methodol. was applicable for delivering various relevant mols. such as pyridopyranoquinolindiones, thienopyranoquinolinones, and indolopyranoquinolinone. The reaction proceeds via cascade C-H activation, carbene insertion and intramol. lactonization. The reaction exhibits highed atom economy, good functional group tolerance and high regioselectivity. The synthesized compound can also behave as a potent fluorescence sensor for Fe3+ ion. In the experiment, the researchers used many compounds, for example, 3,4-Dichlorobenzamide (cas: 2670-38-4Recommanded Product: 3,4-Dichlorobenzamide).
3,4-Dichlorobenzamide (cas: 2670-38-4) 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. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Recommanded Product: 3,4-Dichlorobenzamide
