A nickel-catalyzed site-selective tandem cyclization of 1,6-diynes with substituted indolines or indoles through consecutive dual C–H bond activation is described. In the reaction, fused indole and carbazole derivatives were observed in good to excellent yields, which three C–C bonds formed one pot. Later, presence DDQ, aromatization indoline derivative was converted derivative. possible reaction mechanism involving as a key step proposed account for present reaction.

Abstract Cycloaddition reactions serve as exceptionally useful strategy to provide atom‐economical, efficient and practical access complex molecules from simple starting materials. The [4+2]‐cycloaddition reaction allows for the stereospecific construction of six‐membered carbo‐/heterocycles. catalyzed by transition metals are potent methods rapid highly functionalized molecular frameworks. This review article summarizes different reports on transition‐metal involving various such Pd, Cu, Rh, Au, Fe, Ni, Sc, Sn, Hf, Ag, Mn, Dy, Co etc. straightforward pharmaceutically active heterocycles. An emphasis is laid mechanistic insights highlight unique application novel processes transition‐metals in these transformations build intricate polycyclic structures.
