Abstract

Much effort has been devoted to the synthesis of α-amino acids in enantiomerically pure form, and this subject has been covered by several general reviews.1, 2 and 3Amongst the different methods reported in these reviews, asymmetric protonation of enolates is rarely reported; however it is a very efficient method since it permits the conversion of a racemic compound into the desired enantiomer. ... Duhamel et al.[4]have centred their research on the deprotonation of ...
