A novel and general route for the solid phase synthesis of N-substituted α-aminoacids has been developed. This synthesis employs Fukuyama's 2-nitrobenzenesulfonamide protecting group for preparation of secondary amines. The versatility of this methodology is demonstrated by the facile synthesis of a trisubstituted diketopiperazine (DKP) skeleton.

(EN) The use of cholecystokinin and derivatives of cholecystokinin for inducing miosis in the eye (pupil constriction) $i(after) certain types of examinations and operations. Furthermore, the use of antagonists to cholecystokinin and derivatives of these for preventing miosis in the eye, for example $i(during) surgery and in cases of uveitis. The invention moreover also comprises ophthalmological compositions containing an active amount of cholecystokinin or of its derivatives or antagonists.(FR) Utilisation de cholécystokinine et dérivés de cholécystokinine pour induire le myosis (constriction de la pupille) $i(après) certains examens et opérations.
