Two-step conversion of aldehydes to 2-monosubstituted aziridines has been extended to sugar derivatives. Treating O,O′-isopropylidene-D-glyceraldehyde with benzenesulfonyl chloride and sodium cyanide, 2-benzenesulfonyloxy-3,4-isopropylidenedioxybutyronitrile is obtained as a mixture of the diastereomers in a good yield, and is converted to the corresponding ketalaziridine, 2-(1,2-isopropylidenedioxyethyl)aziridine
