Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1117-71-1, Name is Methyl 4-bromobut-2-enoate, molecular formula is C5H7BrO2, belongs to esters-buliding-blocks compound, is a common compound. In a patnet, author is Xie Jianwei, once mentioned the new application about 1117-71-1, Recommanded Product: Methyl 4-bromobut-2-enoate.
Transition-Metal-Free Decarboxylative Amidation of Aryl alpha-Keto Acids with Diphenylphosphoryl Azide: New Avenue for the Preparation of Primary Aryl Amides
In this paper, a novel transition-metal-free decarboxylative amidation of aryl alpha-keto acids with diphenylphosphoryl azide (DPPA) under mild conditions has been developed. The reaction proceeded smoothly to afford the corresponding primary aryl amide products in good to excellent yields under air and showed excellent functional group tolerance. Gram-scale reaction was also performed to produce the desired product in high yield. In addition, the mechanism of the present reaction was investigated.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1117-71-1. The above is the message from the blog manager. Recommanded Product: Methyl 4-bromobut-2-enoate.
