In this letter, we report a palladium-catalyzed enyne cycloisomerization of linear peptides to generate small cyclic peptides embedded with a conjugated 1,3-diene. The utility of these resulting macrocyclic dienes is demonstrated by carrying out [4+2] cycloadditions with dienophiles to generate constrained cyclic peptides with cyclic linkers.
在这封信中,我们报道了线性肽的钯催化烯炔环异构化,以生成嵌入有共轭1,3-二烯的小环肽。这些产生的大环二烯的实用性通过与亲双烯体进行[4 + 2]环加成反应生成具有环接头的受限环肽来证明。
