reaction features an electrophilic “I+” mechanism, which is importantly quite different from and milder than the typical radical-involving process, and can be readily amplified for the total synthesis of (+)-WIN 64821.
一种简便和对环境无害的KI(催化量)/ NABO 3 ·4H 2 O型氧化系统已被开发用于串联氧化aminocyclization /耦合
色胺,得到一系列3一,3一'-bispyrrolidino [2,3- b高效率的二氢
吲哚(产率高达94%)。该反应具有亲电性“ I + ”机理,这一机理与典型的自由基引发过程有很大不同,并且温和得多,可以很容易地被放大以合成(+)-WIN 6482。
