P. Dallemagne et al., A NEW-TYPE OF TRIFLUOROACETYLAMINO ANCHIMERIC ASSISTANCE IN A CYCLOPENTANE RING, Heterocyclic communications, 2(2), 1996, pp. 185-188
Treatment in alkaline medium of a gamma-bromotrifluoroacetylaminocyclo
pentane derivative affords a bridged oxazepine whose cleavage led sele
ctively to trans substituted compounds. This anchimeric assistance rea
ction due to a trifluoroacetylamino group beared by a cyclopentane rin
g is similar to those observed with the opening of aziridines in homol
ogous structures.
