A procedure converting tribromocyclopropane to densely functionalized 尾-selenocyclopropylboronic ester using the 1,2-metalate rearrangement of a boron ate-complex has been developed. Treatment of an in situ-generated cyclopropenylboronic ester ate-complex with phenylselenenyl chloride triggered stereospecific rearrangement to produce functionalized cyclopropanes. DFT calculations for 1,2-metalate rearrangement suggested that the reaction proceeds through a seleniranium intermediate. In the experiment, the researchers used many compounds, for example, 2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4Product Details of 14204-27-4).
2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4) belongs to indole derivatives. Indole, first isolated in 1866, and it is commonly synthesized from phenylhydrazine and pyruvic acid, although several other procedures have been discovered. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Product Details of 14204-27-4
