Reaction of ruppert’s reagent (TMS-CF3) with Oxazolidinones: Synthesis of protected α-amino trifluoromethylketones
摘要:
(Trifluoromethyl)trimethylsilane adds to alpha-amino acid derived oxazolidin-5-ones in excellent yields. The adducts can be converted into protected alpha-amino trifluoromethylketones by acid hydrolysis.
The reaction of benzyloxycarbonyl-5-oxazolidinones with alcohols and sodium hydrogen carbonate to afford the corresponding benzyloxycarbonyl esters is described.
