## Abstract We compare in this contribution the aggregation and the rotational side‐chain isomerism of the diastereomeric cyclodipeptides phenylalanine‐pipecolic acid (1, 2) with those previously observed^1^ in the parent DKP's, containing the 4‐thiapipecolic acid moieties instead. Concomitantly wi
