Deuterium labelling aziridination

Scheme 2 Deuterium labeling experiment to determine diastereoselectivity in zircona-aziridine formation...

Fig. 4.17a). By means of deuterium labeling experiments and analyses of structurally related compounds,concise information on fragmentation pathways was obtained (Scheme 4.10a). Ring opening processes of the protonated molecule (m/z 210) accompanied by the losses of methylamine (-31 Da) or 1-methyl-aziridine (-57 Da) yielded major product ions at m/z 179 and 153, which were assigned to a charged...
