Chan-lam amination
WebIn organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement.. The reaction is highly …

WebAug 22, 2024 · Abstract. This review summarizes the current state-of-the-art procedures in terms of the preparation of N -arylindoles. After a short introduction, the transition-metal-free procedures available for the N -arylation of indoles are briefly discussed. Then, the nickel-catalyzed and palladium-catalyzed N -arylation of indoles are both discussed. WebChan-Lam Coupling.
