Functionalized epoxides are regioselectively opened using trimethylsilyl azide/aluminum isopropoxide giving 2-trimethylsiloxy azides by attack on the less substituted carbon.

The ring-opening of functionalized epoxides with trimethylsilyl azide in the presence of a catalytic amount of Ti(O-i-Pr)4 or Al(O-i-Pr)3 is described. The reaction is stereospecific and highly regiospecific, leading generally to the formation of the carbon-azido bond on the less substituted carbon. The mechanism of this reaction is also discussed.
