Article abstract of DOI:10.1016/S0040-4039(97)01282-3

Macrocyclic dioxadilactam 2 was obtained in two steps from R-(-)-phenylglycinol via the chiral amido-ketal 1. Cyclization of 1 in acidic conditions (PTSA) and concentrated solution (9 = 0.15 M) afforded 2 as three diasteromers 2a+2b+2c, two of which show a C-2 symmetry.
