Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 5306-85-4, Name is (3R,3aR,6S,6aR)-3,6-Dimethoxyhexahydrofuro[3,2-b]furan, molecular formula is , belongs to pyrrolines compound. In a document, author is Erden, Ihsan, Recommanded Product: 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.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5306-85-4, in my other articles.
