Here we illustrate a new method for the rapid determination of ee’s of chiral alcohols using the thermally-stable, non-chiral lithium aluminate reagent [EtAl(6-Me-2-py)$3$Li] (1). $In\; situ$ reaction of the alcohols with 1 produces robust dimers in solution, present as diastereomeric pairs ($SS/RR$ and $RS$) with distinct resonances in their $1$H and $7$Li NMR spectra. The ee can be calculated simply from integration of the $1$H and/or $7$Li NMR spectra.
