The title compounds were prepared through a synthetic sequence involving: (i) a reaction of the condensation product between an enantiopure β-amino alcohol and an aldehyde with allylmagnesium chloride; (ii) an N-allylation of the resulting secondary amine; (iii) a chemoselective cleavage of the β-amino alcohol residue; and (iv) a protection of the secondary amine followed by a ring closing metathesis. The advantageous use of (1R,2S)-norephedrine was demonstrated in these syntheses.
