Resin-bound dendrimers as high loading supports for solid phase chemistry
摘要:
The synthesis of a tris-Boc tri-amino acid and its utility in the generation of dendrimers as inert scaffolds on solid supports is described. These high loading amine functionalized resins were successfully used in the syntheses of small molecules, (C) 1999 Elsevier Science Ltd. All rights reserved.

Anomalous amino acids not only play central roles as mimics of natural amino acids but also offer opportunities as unique building blocks for combinatorialchemistry. This paper describes the chiral syntheses and solid-phase applications of a versatile atypical amino acid, 4-azalysine (2,6-diamino-4-azahexanoic acid) 1. The syntheses of differentially protected 4-azalysine derivatives 28a-e have been
