Unprecedented use of 29Si NMR spectroscopy for a convenient determination of enantiomeric excesses of chiral α-C-silylated amines and alcohols†
Abstract
The use of routine refocused-decoupled INEPT 29Si NMR spectroscopy, in the presence of the chiral lanthanide shift reagent Eu(tfc)3, allows convenient enantiomeric excess determination of chiral α-C-silylated amines and alcohols for the first time.
