Abstract The reaction of N-benzyl α-amino acid ethyl esters with ethylmagnesium bromide in the presence of a catalytic amount of titanium tetraisopropoxide leads to formation of the corresponding 1-aminoalkyl-1-cyclopropanols in high yields. Hydrogenation of the latter over palladium catalyst ensures selective removal of one or two protecting benzyl groups from the nitrogen atom.
