Dibromophenols are a group of bromophenols consisting of one hydroxy group and two bromine atoms bonded to a benzene ring. There are six structural isomers , each with the molecular formula C 6 H 4 Br 2 O, which differ by arrangement of the substituents.
The first step is the oxidation of the aniline 1 using tert-butyl hypochlorite (tBuOCl) to give the chloramine 2. The second step is the addition of the keto-thioether to give the sulfonium ion 3, and is typically done at low temperatures (−78 °C). The third and final step is the addition of a base, which in this case is triethylamine.
6,6'-Dibromoindigo is an organic compound with the formula (BrC 6 H 3 C(O)CNH) 2. A deep purple solid, the compound is also known as Tyrian purple, a dye of historic significance. Presently, it is only a curiosity, although the related derivative indigo is of industrial significance. It is produced by molluscs of the Muricidae species. [1]
The compound is based on the indole structure, but the 2-3 bond is saturated. By oxidation/dehydrogenation it can be converted to indole. [1] [2] Indoline can be produced from the reaction of indole, zinc and 85% phosphoric acid. [3] It was used to make Indocaine.
Eosin B is a form of eosin which is a dye compound. [1] [2] There is another form [3] of eosin B dye and its chemical name is 4, 5-dibromo-2, 7dinitro- fluorescein or 4′,5′-dibromo-2′,7′-dinitro-3-oxo-3Hspiro[2-benzofuran-1,9′-xanthene]-3′,6′ diolate. [3]
Later, series of more selective c-Met inhibitors were designed, where an indolin-2-one core (encircled in figure 1) was present in several kinase inhibitors. SU-11274 was evolved by substitution at the 5-position of the indolinone [ 9 ] and by adding a 3,5-dimethyl pyrrole group, PHA-665752 was evolved [ 11 ] – a second-generation inhibitor ...
