An iron-catalyzed acyl-azidation of alkenes under mild reaction conditions has been developed. Aromatic aldehydes or aliphatic aldehydes can be used as the acyl radical precursors; TMSN3 is used as the azido source; TBHP is the initiator. The synthesized unsymmetrical β-azido ketones can be easily transformed into valuable functionalized compounds, such as γ-aminol, γ-azido alcohol, β-azido oxime,

Chromioenamines can be generated by treatment of O-acetyloximes with chromium(II) via two steps of one-electron reduction and successive isomerization, and the species react with aldehydes to give gamma-amino alcohols after reduction with LiAlH4.

β-hydroxy ketone O-benzyl oximes with lithium aluminum hydride in the presence of sodium or potassium methoxide afforded the corresponding syn-β-amino alcohols in highly stereoselective manner. A lythraceae alkaloid, lasubine II, was synthesized stereoselectively by applying this method.

An efficient and highly regioselective protocol was developed for the preparation of 5-hydroxy-2-isoxazolines, which have been proved to be versatile synthons for isoxazles, beta-hydroxy oximes, and gamma-amino alcohols. beta-Lactams, commonly embedded in the skeletons of bioactive natural products, were also synthesized in two steps from beta-hydroxy oximes, providing a new strategy for the synthesis of this kind of compounds.
