Abstract

The ozonation of N-Boc-protected 3-methylidene-4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one resulted in its transformation into 3-hydroxy-4-phenyl-5-(trifluoromethyl)-3-pyrrolin-2-one. Catalytic hydrogenation of its O-Boc-protected derivative introduced a way to reduce the double bond in combination with elimination of the hydroxy group leading to the formation of 4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one as an intermediate in the synthesis of fluorinated E1R structural derivative 2-[5-oxo-3-phenyl-2-(trifluoromethyl)pyrrolidin-1-yl]acetamide.
