Englisch-Peters, Sabine
, p. 6127 - 6134 (1989)
The isomers of γ-hydroxy-valine (6) were prepared by a modified Erlenmeyer synthesis and the δ-hydroxy analogues each of leucine (16a) and isoleucine (16b) were synthesized via 1,4-Michael addition.The diastereomers of 6 could be separated by column chrom
