実験手順

A solution in toluene of N-ethylmaleimide, HN3 (excess relative to the maleimide), and the (salen)AlN3 catalyst depicted above (10 mol % relative to the maleimide) was maintained at −30° C. for 18 h. After a standard quench and work-up of the reaction mixture, the crude material was purified to yield 2-azido-N-ethylsuccinimide (93%, 93% ee).
