The intramolecular Schmidt reaction of simple azido secondary benzyl alcohols has been realized for the first time. Investigation of the electronic and steric effects of the substrates on the product outcome was conducted. Unique intramolecular Schmidt rearrangements were observed with the formation of a cinnamaldehyde derivative and aryl aldehydes, respectively. Using this protocol, an efficient synthesis of dihydrobenzotriazine derivatives was achieved. Moreover, a practical approach to 2-aryl-1-pyrrolines was also accessed.

Five endophytic yeast strains isolated from edible plants were tested in the reduction β-chloro- and β-azidopropiophenone for the preparation of optically active fluoxetine precursors. The biotransformation rendered not only the corresponding chiral γ-substituted alcohols, but also unsubstituted alcohols and ketones. The product profile was studied and a plausible mechanism for the reductive elimination of the β-functional group is proposed.

An enantioselective synthesis of chiral γ-azidoalcohols via lipase-catalyzed resolution is described. The efficiency of various lipases and the effect of different solvents have been studied. Pseudomonas cepacia immobilized on diatomaceous earth (PS-D) in n-hexane catalyzed the transesterification process in an efficient manner providing γ-azidoalcohols in high enantiomeric excess.
