Addition of BrCCl3 to methyl N-acryloyl-(S)-prolinate (1) catalyzed by Ft(CO)(5) or Fe(CO)(5)-PPh(3) at 75-80 degrees C in benzene solution affords in good total yield methyl N-((S)-2-bromo-3,3,3-trichlorobutyryl)-(S)-prolinate and methyl N-((R)-2-bromo-3,3,3-trichlorobutyryl)-(S)-prolinate (3) in an similar to 1.5:1 ratio, which does not depend on the catalytic system employed or its concentration. Catalysis by the Fe(CO)(5)-PPh(3) system substantially increases the adducts yield.
