The synthesis of 5-(alditol-1-C-yl)-hydantoin derivatives was performed via diastereoselective aldol-type addition of 1,3-dibenzyl-hydantoin to enantiopure aldehydo sugars. Starting from the d-ribo-configured 5-(alditol-1-C-yl)-hydantoin template, the synthesis of (2R,3S,4R)-3,4,5-trihydroxynorvaline was carried out.

The shortest route at present for the asymmetric synthesis of 3,4-diepipolyoxamic acid 2 and the isomer of polyoxamic acid 5 has been developed via the diastereoselective aldol reaction of carnphor-based tricyclic iminolactones 3 and 4 with good stereoselectivities (dr: 12:1 and 9:1) and high yields.
