Chemical Research Letters, May 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. Which mentioned a new discovery about category: benzodioxans, category: benzodioxans
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 %.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: benzodioxans, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 22013-33-8, in my other articles.
