Air-/moisture-stable, crystalline, and storable chiral salicyloxazoline based oxorhenium(V) complexes have been synthesized and their catalytic application for the asymmetric reduction of ketimines using hydrosilane as hydride source is disclosed. A broad substrate scope, high yields, and excellent enantioselectivities (up to 99 %) are attained. Furthermore, the syntheses of enantiopure α-amino esters, γ- and δ-lactams, and isoindolinones have also been carried out using this methodology. Finally, the method has been applied to synthetic targets of pharmaceutical relevance, such as R-(+)-salsolidine and R-(+)-crispine A.

Here we describe a new, efficient general synthesis of o-acetylphenylacetic acids by Heck palladium-catalyzed arylation of n-butyl vinyl ether with o-bromophenylacetic acids, and its application to the synthesis of indolo[2,3-b]naphthalene-6,11-diones.
