Control of the enantiomeric purity and correlation with the absolute configuration of N-protected 2-cyanoglycinates
摘要:
The enantiomeric purity of substituted N-phthaloyl-2-cyanoglycine methyl esters obtained by resolution of covalent diastereoisomers was easily established by measuring the shift separation of signals using Eu(hfc)3. A correlation with the absolute configuration of enantiomers was observed.
