G. Cardillo et al., Influence of Lewis acids on the regioselectivity of N-Boc-aziridine-2-carboxylate microwave-assisted rearrangement, SYNLETT, (9), 2000, pp. 1309-1311
The microwave assisted rearrangement of N-Boc-chiral aziridine-2-imides and
esters to oxazolidin-2-ones in the presence of different Lewis acids is pr
esented. The regioselectivity of the reaction strongly depends upon the Lew
is acid selected and the reaction conditions.
