Acyl oximes derived from a variety of indolylalkanones underwent a ring closure sequence during FVP to afford 9H-pyrido[2,3-b]indoles. Unlike UV light promoted reactions of oxime esters, the mechanism is almost certainly not mediated by iminyl radicals but probably involves tautomerism, elimination of acetic acid, and a final electrocyclic ring closure.
衍生自多种吲哚基链烷酮的酰基肟在FVP期间进行了闭环反应,得到9H-吡啶并[2,3-b]吲哚。与紫外线促进的肟酯反应不同,该机理几乎可以肯定不是由亚氨基自由基介导的,而是可能涉及互变异构,乙酸消除和最终的电环闭合。
