Research speed reading in 2021. Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent，Which mentioned a new discovery about 17680-55-6, molcular formula is C9H10BrN, introducing its new discovery. , 17680-55-6
An efficient synthesis of a variety of quinazolinone derivatives via a direct cyclization reaction between commercially available anthranils and cyclic amines is described. The developed transformation proceeds with the merits of high step- and atom-efficiency, a broad substrate scope, and good to excellent yields, without additional catalysts, and offers a practical way for the preparation of rutaecarpine and its derivatives with structural diversity.
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 17680-55-6, help many people in the next few years.17680-55-6
