Hexafluoroacetone → 2-[(4S)-3-(3,3-dimethylbutyl)-5-oxo-2,2-bis(trifluoromethyl)-1,3-oxazolan-4-yl]acetic acid

참여 물질

반응 단계

A gas flow of hexafluoroacetone is blown at a moderate rate at room temperature onto an intensely stirred suspension of 10 mmol of N-(3,3-dimethylbutyl)-L-aspartic acid in 20 ml 1,4-dioxane. A clear solution is formed overnight. The solvent was removed in vacuo, and the oily residue was confirmed to be an almost quantitative amount of 2-[(4S)-3-(3,3-dimethylbutyl)-5-oxo-2,2-bis(trifluoromethyl)-1,3-oxazolan-4-yl]acetic acid by NMR.
