No full textPalladium-catalyzed aerobic oxidative cyclization of N-aryl imines : indole synthesis from anilines and ketones
No full textWe report here an operationally simple, palladium-catalyzed cyclization reaction of N-aryl imines, affording indoles via the oxidative linkage of two C–H bonds under mild conditions using molecular oxygen as the sole oxidant. The process allows quick and atom-economical assembly of indole rings from inexpensive and readily available anilines and ketones and tolerates a broad range of functional groups

No full textO-Acetyl oximes derived from 2′-arylacetophenones undergo N–O bond cleavage/intramolecular N-arylation in the presence of a catalytic amount of iron(III) acetylacetonate in acetic acid. In combination with the conventional cross-coupling or directed C–H arylation, the reaction offers a convenient route to substituted phenanthridines
