The ring opening of epoxides with nucleophiles such as TMSN3 and isopropylamine takes place enantioselectively in the presence of (beta-cyclodextrin under extremely mild conditions and the azido alcohols and amino alcohols are formed as (S)-isomers.

Stereoselective synthesis of (S)-propanolamines has been carried out by the ring opening of racemic epoxides with 2-propylamine in presence of lipases and subtilisin. The effect of solvent towards selectivity has also been studied.
