New Advances in Chemical Research, May 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis.5306-85-4, Name is (3R,3aR,6S,6aR)-3,6-Dimethoxyhexahydrofuro[3,2-b]furan, molecular formula is C8H14O4, belongs to pyrrolines compound, is a common compound. In a patnet, author is Erden, Ihsan, once mentioned the new application about 5306-85-4, SDS of cas: 5306-85-4.
Photooxygenation of 5-dialkylamino-4-pyrrolin-3-ones. synthesis of highly functionalized ureas, 2-oxazolidinones, and 2-oxazolinones
5-Dialkylamino-4-pyrrolin-3-ones, available from cyclocondensation of amidines with dimethyl acetylenedicarboxylate (DMAD), undergo rapid singlet oxygenation to give highly functionalized ureas by way of a 1,2-dioxetane cleavage of the initially formed [2 + 2] cycloadducts. These latter compounds undergo cyclization to 2-oxazolidinones in MeOH. Catalytic hydrogenation of the ureas in EtOAc gives 2-oxazolinones. The DBU-DMAD adduct undergoes photooxygenation by an entirely different pathway to give a large ring heterocycle.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 5306-85-4. SDS of cas: 5306-85-4.
