A novel transformation of N-alkoxycarbonylprolines 1 to 4-trifluoroacetyl-2,3-dihydropyrroles 2 was efficiently realized by utilizing trifluoroacetic anhydride, in which probable intermediates were mesoionic 1,3-oxazolium-5-olates B.
ENANTIOMERIC QUANTIFICATIONS OF AMINO ACIDS THROUGH THEIR Nα-ACYL AMIDES BY GAS CHROMATOGRAPHY.

Apparent separation of 1.1 or higher on Chirasil Val III can be obtained for Nα-acyl N-alkyl aminoacid amides allowing the use of short capillary gas chromatographic columns.A clean derivatization protocol without racemization is described, proceding through the NCA derivatives that are prepared from "in situ" silylated amino acids with trimethylsilyl cyanide.
