摘要
The diastereoselective hydroxylation at C-5 of chiral 6-substituted perhydropyrimidin-4-ones is described. The diastereoselection depends on the base and the hydroxylating agent utilised and on the absolute configuration of the exocyclic phenylethyl moiety. The acid hydrolysis of 5-hydroxy-6-methyl perhydropyrimidin-4 ones furnishes the enantiomerically pure L-isothreonine and D-alloisothreonine.
