An Fe-catalyzed conversion of aldehydes to ketones via [1,2]-shift has been developed. This skeletal rearrangement shows a wide substrate scope and chemoselectivity profile while exhibiting an excellent [1,2]-aryl or [1,2]-alkyl shift selectivity that is easily switched by electronic effects.

An efficient and novel procedure for a copper catalyzed domino coupling reaction has been developed, which afforded various oxindoles in good to excellent yields with tolerance of various substituents. In addition, this method could be applied to synthesize horsfiline and coerulescine in few steps with high total yields. The Royal Society of Chemistry 2012.

(Chemical Equation Presented) A new catalyst system for the intramolecular acylation of aldehydes with aryl bromides via C-H functionalization is described. The transformation is distinguished by a remarkable functional group tolerance and hence allows fo

Two oxindole syntheses are described, both starting from ketones, in which the carbonyl carbon becomes C-3 of the oxindole.The first route uses o-lithioformanilide followed by attack with cyanide ion and hydrolysis.The second uses a pinacol-type rearragement (or the γ-silyl alcohol variation) to create the quaternary centre, and involves an intramolecular displacement of fluoride ion from an unactivated benzene ring by an amide nitrogen to complete the lactam ring.The two routes are stereochemically complementary, giving different spiro-oxindoles from norbornanone.
