Quality Control of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine, We’ll be discussing some of the latest developments in chemical about CAS: 22013-33-8.
A Simple, convenient and highly efficient I2-catalysed approach has been unfolded towards the synthesis of highly fluorescent beta-carboline C-1(3)-tethered thiazolo[4,5-c]carbazoles, naphtho[2,1-d]thiazoles and benzothiazole derivatives using Kumujian C as a template. This domino strategy proceeds through assembly of 1-formyl-9H-beta-carbolines, arylamines and elemental sulfur via formation of one C?N and two C?S bonds in a single operation. Importantly, the methodology was found applicable to beta-carboline acetals also. A diversely substituted library of 37 beta-carboline tethered arylthiazole hybrids was prepared in excellent yields. The strategy was found appropriate for gram scale synthesis also. The photophysical properties of these fluorophores were also estimated and showed excellent fluorescence properties with quantum yield (PhiF) up to 92 %.
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 22013-33-8
