An anomalous Dakin–West reaction of N-carbamate substituted prolines and trifluoroacetic anhydride

Abstract

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.
