The presence of a chain bearing a stereogenic centre at the N-5 position of 1-(1-adamantylmethyl)-3-arylureido-2,4-dioxo-1,5-benzodiazepines induces optical resolution. The synthesis of these compounds and their potency as potential CCK-B receptor antagonists is discussed briefly here. (C) 1998 Elsevier Science S.A.
