Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In a patent, 22013-33-8, name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine, introducing its new discovery. Quality Control of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine
A modular synthetic method for bis- and tris-1,2,3-triazoles that include a benzotriazole structure was developed on the basis of sequential azide-aryne and azide-alkyne cycloadditions. The key to success was efficient halogen-metal exchange reaction-mediated generation of aryne from ortho-iodoaryl triflates bearing a base-sensitive terminal alkyne moiety, which was achieved using trimethylsilylmethyl Grignard reagent.
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 22013-33-8, help many people in the next few years.Quality Control of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine
