A chiral (salen)Al complex catalyzes the highly enantioselective conjugate addition of carbon- and nitrogen-based nucleophiles to various acyclic α,β-unsaturated ketones providing access to a wide range of useful chiral building blocks in high yield and enantiomeric excess.

Amberlite IRA900N3 is an excellent and recyclable organocatalyst for the azidation of α,β-unsaturated ketones with trimethylsilyl azide under solvent-free conditions. This procedure is a green tool for the preparation of β-azido ketones under mild conditions with good yields.

A mild oxidation of selected anions (N3-, SCN-, I-, and Br-) by ceric ammonium nitrate (CAN) in the presence of substituted cyclopropyl alcohols provides β-functionalized ketones in short reaction times. This method provides an alternative pathway to important starting materials and intermediates in organic synthesis.
