Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Category: pyrrolines, 525-76-8, Name is 2-Methyl-4H-benzo[d][1,3]oxazin-4-one, molecular formula is C9H7NO2, belongs to pyrrolines compound. In a document, author is Ricko, Sebastijan, introduce the new discover.
Double Spirocyclization of Arylidene-Delta(2)-Pyrrolin-4-Ones with 3-Isothiocyanato Oxindoles
Arylidene-Delta(2)-pyrrolin-4-ones undergo organocatalyzed double spirocyclization with 3-isothiocianato oxindoles in a domino 1,4/1,2-addition sequence. The products contain three contiguous stereocenters (ee up to 98%, dr up to 99:1, 12 examples). The absolute configuration of the major diastereomer was determined by single crystal X-ray analysis. Along with heterocyclic Michael acceptors based on oxazolone, isoxazolone, thiazolidinone, pyrazolone, and pyrimidinedione, the reported results display the applicability of unsaturated Delta(2)-pyrrolin-4-ones (pyrrolones) for the organocatalyzed construction of 3D-rich pyrrolone-containing heterocycles.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 525-76-8. Category: pyrrolines.
