Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 87-99-0, Name is Xylitol. In a document, author is Kumar, Ravi G. M. V. N. A. R., introducing its new discovery. Quality Control of Xylitol.
The present work reports a simple and efficient method for the sulfenylation of a wide variety of indoles with aryl, benzothiazolethiols using manganese(III) acetate promoted free radical reaction. This method is selective at the C3 position of indoles and offers several advantages such as broad substrate scope, functional group tolerance (bromo, carboxylic acid, methoxy, difluoromethoxy, ester groups) and gives the required products in good to excellent yields. The experimental simplicity makes it a useful and attractive approach for the synthesis of 3-arylsulfenylindoles. The compounds 1-12 are evaluated for the anti-bacterial agents. Most of them exhibited promising activities.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 87-99-0 help many people in the next few years. Quality Control of Xylitol.
