In the present work, a novel stereoselective radical cyclization/oxidation/spirocyclization cascade process using a mixture of n-Bu3SnH/ dilauroyl peroxide is described. The proposed mechanism for this later process combines a 6-endo cyclization of an aryl radical onto an enamide double bond, and a consecutive oxidative-ionic spirocyclization at C-3 of an indole nucleus. All processes led to the construction
在当前的工作中,描述了使用n -Bu 3 SnH /过氧化二月桂酰的混合物的新颖的立体选择性自由基环化/氧化/螺环化级联方法。所提出的机制对这个后面的过程结合了6-内切在吲哚核的C-3的芳基上的烯酰胺双键,并且连续氧化离子螺环环化。所有过程都导致从相对简单的原料开始的一步合成中构建新的螺螺吲哚衍生物。有机过氧化物似乎起引发剂和氧化剂的作用。
