• (Scheme 4). Reduction using lithium aluminium deuteride led to the insertion of the label at the benzylic position. Oxidation to the aldehyde followed by condensation with tosylamide afforded the deuterated imine 6. Aziridination using the sulfonium ylide generated in situ from 7 proceeded smoothly to
