Mw. Walter et al., REACTION OF RUPPERT REAGENT (TMS-CF3) WITH OXAZOLIDINONES - SYNTHESISOF PROTECTED ALPHA-AMINO TRIFLUOROMETHYLKETONES, Tetrahedron letters, 36(42), 1995, pp. 7761-7764
(Trifluoromethyl)trimethylsilane adds to alpha-amino acid derived oxaz
olidin-5-ones in excellent yields. The adducts can be converted into p
rotected alpha-amino trifluoromethylketones by acid hydrolysis.
