Organoaluminum reagents of type R1R2NAlR2 allow highly stereospecific oxirane ringopening producing allylic alcohols under mild conditions. trans-Epoxycyclododecane is converted to (E)-2-cyclododecen-1-ol by reaction with diethylaluminum 2,2,6,6-tetramethylpiperidide (DATMP) in quantitative yield, while the cis-isomer gives only 8% yield of the same alcohol. Furthermore, this reagent enables us to
