chiral derivatizing agents, 3-arylcarbonyl-2,2-dimethyl-oxazolidine-4-carboxylic acids (N-arylcarbonylpseudoprolines), were prepared through a simple, short-step synthesis. The absoluteconfiguration of secondary alcohols can be assigned on the basis of the NMR spectroscopic chemical shift difference between diastereomeric pseudoproline esters. Preparation of more efficient agents was achieved simply
