Aziridinyllithiums 4a and 4b, which are stable at low temperature, can be g
enerated by deprotonation of 3a and 3b. Oxazolinyl aziridines 5a-j and 6a-b
have been prepared by the reaction of oxazolinyl aziridinyllithiums 4a and
4b with electrophiles. Aziridines 6c and 6d were, instead, synthesized by
a Darzens-like reaction from 2-(1-chloroethyl)-2-oxazoline 1b. (C) 1999 Els
