Highly enantioselective synthesis of (R)- and (S)-2-amino-5-phosphonopentanoic acids [(R)- and (S)-AP5] via modified Seebach imidazolidinones

The preparation of four new stereoisomeric 1-carbobenzyloxy-2-tert-butyl-3-(α-methylbenzyl)-1,3-imidazolidin-4-o nes is described. Alkylation of the lithium enolates of these chiral glycine derivatives proceeds with high diastereoselectivity. In particula

Alternative Method for the Resolution of 1-Benzoyl-2-tert-butyl-3-methyl-1,3-imidazolidin-4-one

The title heterocycles, which are useful chiral precursors for the asymmetric synthesis of α-amino acids, an be prepared in enantiomerically pure form via the separation of diastereomeric derivatives incorporating (S)-α-methyl-benzylamine.
