Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 3416-57-7, name is 2-(2-Oxopropyl)isoindoline-1,3-dione, A new synthetic method of this compound is introduced below., category: indolines-derivatives
A solution of 123 g of pyridinium bromide perbromide in 600 ml of THF was slowly added dropwise to 2-(2-oxopropyl)-1H-isoindole-1,3 (2H)-dione (70 g; 0.345 mol) in 600 ml of THF, and the mixture was then stirred for about 3 h. For workup, the precipitated solids were filtered off, and the mother liquor was concentrated, taken up in ethyl acetate and thoroughly washed with aqueous bisulfite solution. Drying and concentration afforded 150 g of a yellow oil, which was stirred with methyl tert-butyl ether. 63.4 g; m.p.: 142 to 143 C.; ESI-MS [M+H+]=283.95
The synthetic route of 3416-57-7 has been constantly updated, and we look forward to future research findings.
