The first synthesis of the N-protected α-fluoro-α-amino acid esters 12, 13, 21 and 22, and the corresponding acids 16 and 24, is described.Reaction of ethyl and t-butyl bromofluoroacetates 4 and 9 with di-t-butyl and dibenzyl iminodicarboxylate potassium

New mixed alkyl benzyl imidodicarbonates were prepared by reaction of benzyloxycarbonyl isocyanate with appropriate alcohols.This simple procedure also furnished alternative, more convenient routes to dibenzyl and benzyl 9-fluorenylmethyl imidodicarbonates.The substances are of interest as potential Gabriel reagents.Completely selective removal of one of the alkoxycarbonyl groups from the N-atom of the imidodicarbonates was demonstrated in several instances, giving benzyl carbamate or the alternative carbamate.

In order to study the ring expansion of N-aminoaziridines into N-amino-5-membered heterocycles, N-(dibenzyloxycarbonylamino)aziridines were synthesized.N,N-Dibenzyloxycarbonylhydrazine was prepared.It was then oxidized with lead tetraacetate to a new diacylaminonitrene.This nitrene was added to various olefins to give the corresponding N-protected aminoaziridines.Cleavage of the protecting groups was realized for one example.
