Aziridine-2-carbonitrile rac-1 was hydrated enantioselectively in aque
ous medium by using methylethyl)-2-methyl-3-oxocyclohexanecarbonitrile
(2) as chiral catalyst. The ee value of the unreacted (S)-(-)-aziridi
ne-2-carbonitrile 1 depends on the conversion and reaches greater than
or equal to 99%.
