Three distinct synthetic routes to the 2-prenyl tryptophan core skeleton of tryprostatins and their total syntheses are described. The strategies include a traditional gramine-mediated coupling reaction, Fürstner indole synthesis, and our radical-mediated indole synthesis from o-alkenylphenyl isocyanide. The establishment of reliable conditions for the radical-mediated construction of indoles via a
描述了三种不同的合成途径,它们连接到胰前列腺素的2-异戊二烯色氨酸核心骨架及其总合成物上。该策略包括传统的禾本科胺介导的偶联反应,Fürstner吲哚合成,以及我们由邻烯基苯基异氰酸酯进行的自由基介导的吲哚合成。通过低温自由基引发剂V-70(2,2'-偶氮二(4-甲氧基-2,4-二甲基戊腈))为吲哚进行自由基介导的结构的建立建立可靠的条件导致了Tryprostatins的高效合成A和B。
