One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 525-76-8, Name is 2-Methyl-4H-benzo[d][1,3]oxazin-4-one, formurla is C9H7NO2.

Synthesis of Spiro-Delta(2)-Pyrrolin-4-One Pseudo Enantiomers via an Organocatalyzed Sulfa-Michael/Aldol Domino Sequence
Delta(2)-Pyrrolin-4-ones undergo organocatalyzed sulfa-Michael/aldol domino spirocyclizations with mercaptoacetaldehyde dimer. The products contain three contiguous stereocenters (ee up to 99%, dr up to 95:5, 25 examples) and can be transformed into analogues of natural products. With the use of a single catalyst, the absolute configuration of the products were determined by the configuration of the exocyclic double bond of the starting material. These results point at the possibility of a widespread use of unsaturated Delta(2)-pyrrolin-4-ones in various (organo)catalyzed (cascade) transformations for accessing libraries of 3D-rich pyrrolone-based (spiro)heterocycles.
