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.
