An I2-mediated annulation of 3-aminopyrazoles with indole-3-carboxaldehydes has been demonstrated for the first time. This tandem strategy allows facile construction indole-pyrimidine-pyrazole-fused tetracyclic heteroarenes that are otherwise inaccessible by existing methods. These fused heterocycles exhibited enhanced antifungal activities against Valsa mali and Botryosphaeria dothidea compared commercial Xemium fungicide.

The palladium-catalyzed synthesis of bis-heterocyclic spirocycles containing both pyrroline and indoline motifs is reported. Di-tert-butyldiaziridinone used to functionalize palladacycles generated in situ via domino Narasaka–Heck/C–H activation reactions. reaction readily scalable, the spirocyclic products can undergo deprotection, reduction, (3 + 2) cycloadditions, highlighting their synthetic utility. Additionally, kinetic isotope effect experiments support a turnover-limiting C–H functionalization step catalytic cycle.
