HPLC of Formula: 885272-25-3. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-(5-Methoxy-2-oxoindolin-3-yl)acetic acid, is researched, Molecular C11H11NO4, CAS is 885272-25-3, about Mechanistic study of reversible solid-state melt isomerization of 2-oxindoles to 2-quinolinones and its occurrence in a mass spectrometer. Author is Martinez-Gudino, Gelacio; Perez-Rojas, Nadia A.; Trujillo-Serrato, Joel J.; Mora-Perez, Yolanda; Suarez-Castillo, Oscar R.; Morales-Rios, Martha S..

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

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Natural Product Communications called Preparation of O-methyl substituted 2-oxofuro- and 2-oxopyrrolidinoindolines by reductive lactonization of oxindolylacetic acids, Author is Morales-Rios, Martha S.; Rivera-Becerril, Ernesto; Lopez-Camacho, Perla Y.; Perez-Rojas, Nadia A.; Suarez-Castillo, Oscar R., which mentions a compound: 885272-25-3, SMILESS is COC2=CC=C1NC(C(C1=C2)CC(=O)O)=O, Molecular C11H11NO4, COA of Formula: C11H11NO4.

A practical procedure for the preparation of O-methyl-substituted 3a,8-dialkyl-2-oxofuroindoline derivatives was described. A reductive lactonization of the corresponding (oxindolyl)acetic acids provides a route for the formation of this class of compounds Further transformation of 2-oxofuroindolines into 2-oxopyrrolidinoindolines and then to pyrrolidinoindolines demonstrates their versatility as key intermediates in natural products synthesis. The results of single-crystal X-ray crystallog. analyses are given for five of the studied compounds The title compounds thus formed included a 3,3a,8,8a-tetrahydro-2H-furo[2,3-b]indol-2-one (furanone) derivative (I) and (3aR,8aS)-rel-1,2,3,3a,8,8a-hexahydro-5-methoxy-1-methyl-3a,8-bis(phenylmethyl)pyrrolo[2,3-b]indole (II) and related compounds, such as 5-methoxydebromoflustramine B. The synthesis of the target compounds was achieved using 2,3-dihydro-5-methoxy-1H-indole-3-acetic acid derivatives as key intermediates.
