And the article was included in Journal of Molecular Structure in 2019.Application In Synthesis of 2-(5-Methoxy-2-oxoindolin-3-yl)acetic acid The following contents are mentioned in the article:
An eco-friendly equilibrated rearrangement of a series of 2-oxo-3-indolyl acetic acids (1) with 2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid derivatives (2) was investigated through a solid state melt reaction (SSMR). Mechanistic insight into the thermal rearrangement is provided by 13C-isotopic labeling. The standard mass spectra of 1 and 2 were virtually identical preventing their reliable identification. Reversible interconversion of 1 and 2 was evidenced to occur in the inlet system of a mass spectrometer under electron impact conditions. Relative abundances of fragment ions were found to be a function of temperature This study involved multiple reactions and reactants, such as 2-(5-Methoxy-2-oxoindolin-3-yl)acetic acid (cas: 885272-25-3Application In Synthesis of 2-(5-Methoxy-2-oxoindolin-3-yl)acetic acid).
2-(5-Methoxy-2-oxoindolin-3-yl)acetic acid (cas: 885272-25-3) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD).
