2-amino alcohol derivatives 2a–p by reaction with allylsilane 3 and a catalytic amount of TfOH to give the tertiary homoallylic ethers 8a–o and 9a–e is described. The best results were obtained with the 2-amino alcohol derivative 2p which affords a stereoselectivity of 18:1 even for the allylation of ethyl methyl ketone. The ethers 8 and 9, which contain a phenyl group at C-1 of the amino alcohol moiety
