Md. Andrews et al., CONVENIENT SYNTHESIS OF ENANTIOPURE CYCLIC ALPHA-HYDROXYALKYL ALPHA-AMINO ESTERS, Journal of the Chemical Society. Perkin transactions. I, (3), 1996, pp. 227-228
The preparation of cyclic alpha-hydroxyalkyl alpha-amino esters, the r
ing size of which varies varies from 4 to 7 members, in enantiopure fo
rm is readily achieved by intramolecular alkylative cyclisation of oxa
zolidine precursors.
