The homochiral products of such couplings--1,2-diols, 1,2-diamines, and 1,2-diaminoalcohols--are of particular interest.
This principle is effective only if the meso or 'heterochiral' complex ([ML.sub.R][L.sub.S]) is less active/more stable than the 'homochiral' complex ([ML.sub.R][L.sub.R]) or its derivative.
Following derivatization of MDMA and MDA using (R)-MTP chloride as a homochiral derivatizing agent (HCDA), the diastereomeric amides formed were resolved using the chromatographic conditions used for the analysis of both plasma and urine samples (Figs.

Design that lessens therapeutic doses without increasing overall potency is already occurring with the emphasis on enantiomerically pure drugs (homochiral drugs), which can have therapeutic advantages over their conventional racemic mixtures.
It was clear from many presentations that chiral asymmetric synthetic methods have reached a high level in the past several years and many approaches have now been optimized to make the construction of essentially homochiral synthons from achiral starting materials a practical reality for the modern synthetic chemist.
