## Abstract Optically active α‐deuterated serine dipeptide active ester derivatives were prepared to study the racemization mechanism. N‐Acetyl‐O‐benzyl‐DL‐serine, __1__, was converted to 5(4H)‐oxazolone __2__ and deuterated with CH~3~‐COOD in α‐position. 5(4^2^H)‐Oxazolone __3__ was converted to Z
THR empirical Conformational Asymmetry Rule 192 permits the assignment of absolute configuration to a number of compounds having both deuterium and hydrogen at the asymmetric center; these configurations are consistent with those assigned on mechanistic grounds.3 Thus, butane-2-d, in the indicated a
Correlations are observed between the optical rotation of cr-pinenes and sitespecific isotope ratios, (D/H)i, determined by natural abundance deuterium NMR (SNIF-NMR). The optical purity can therefore be estimated by NMR without the need for spectral separation of the enantiomers.
