一般描述

2-(Trifluoroacetyl)pyrrole, an α,α,α-trifluoromethyl ketone is a 2-substituted pyrrole derivative. It has been synthesized by reacting pyrrole with trifluoroacetic anhydride in benzene at 0℃. Its enantioselective hydrogenation to form corresponding alcohol using 5wt.% Pt/Al₂O₃ catalyst chirally modified by new synthetic chiral amines has been investigated.
