CLEAR YELLOW TO BROWN-RED LIQUID

Definition

ChEBI: A benzoxazole in which the benzene ring is fused to a 1,2-oxazole ring across positions 3 and 4.

General Description

Anthranil undergoes thermal decomposition during single pulse shock-tube experiments to form aniline and cyclopentadiene carbonitrile. Surface-enhanced Raman spectrum of anthranil in activated silver colloid has been studied.

The Elimination of Masses 27 and 28 from the + Ion of 2-Nitrotoluene

The expulsion of neutral fragments of masses 27 and 28 from metastable + ions derived from 2-nitrotoluene has been observed.The relative abundances of the resulting fragment ions, together with the kinetic energy released in each process, has been compared with similar fragmentations of + ions derived from other precursor molecules.In this way, the nature of the neutral fragments and the structure of the + ions from 2-nitrotoluene has been investigated.The most likely structure is the 1,2-benzisoxazolenium cation although the coexistence of other structures cannot be ruled out on the present evidence.

Palladium-catalyzed carbonylative cyclization of benzyl chlorides with anthranils for the synthesis of 3-arylquinolin-2(1: H)-ones

An efficient carbonylative procedure for the synthesis of 3-arylquinoin-2(1H)-ones has been established. Through a palladium-catalyzed aminocarbonylation of benzyl chlorides with anthranils, a variety of 3-arylquinoin-2(1H)-one products were obtained in moderate to excellent yields with good functional group tolerance.

Access to acridones by tandem copper(i)-catalyzed electrophilic amination/Ag(i)-mediated oxidative annulation of anthranils with arylboronic acids

An efficient and practical approach for the synthesis of medicinally important acridones was developed from anthranils and commercially available arylboronic acids by a tandem copper(i)-catalyzed electrophilic amination/Ag(i)-mediated oxidative annulation strategy. This new and straightforward protocol displayed a broad substrate scope (25 examples) and high functional group tolerance. What's more, a possible mechanistic proposal was also presented.
