functionalized acyclic chiral pyrroloamide compounds were synthesized by a simple and robust process involving the creation of a C-C bond between unprotected pyrroles and acyclic chiral acrylamides using Lewis acids. This alkylation reaction using Michael acceptors has been optimized, allowing us to obtain channel selective access to monoalkylated or dialkylated pyrroles, in good yields. Di- and tripeptide deriving
通过一种简单而稳健的方法,包括使用路易斯酸在未保护的吡咯和无环手性丙烯酰胺之间建立CC键,合成了多种新型的官能化无环手性吡咯酰胺化合物。使用迈克尔受体的烷基化反应已得到优化,使我们能够以良好的收率选择单烷基化或二烷基化吡咯的通道。二肽和三肽衍生的丙烯酰胺也已经用作反应伙伴。
