Acid promoted alkylation of hydroxy group containing acceptors 3-14 with O-cyclopropylmethyl and O-cyclobutyltrichloroacetimidates 1 and 2, respectively, afforded ethers with cyclopropylmethyl, cyclobutyl, and homoallyl residues as a result of the rearrangement of the cation intermediates. The dependence of product formation on acceptor structure is discussed.
