Selective palladium-catalyzed aminocarbonylation of 1,3-dienes: Atom-efficient synthesis of beta,gamma-unsaturated amides
Carbonylation reactions constitute important methodologies for the synthesis of all kinds of carboxylic acid derivatives. The development of novel and efficient catalysts for these transformations is of interest for both academic and industrial research. Here, the first palladium-based catalyst system for the aminocarbonylation of 1,3-dienes is described. This atom-efficient transformation proceeds under additive-free conditions and provides straightforward access to a variety of beta,gamma-unsaturated amides in good to excellent yields, often with high selectivities.
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 20532-28-9, help many people in the next few years.Safety of 5-Aminobenzothiophene
