A combinatorial library motif has been developed based on orthogonally protected aminodiol scaffolds. Amine functionality was derivatized by commercially available electrophiles including carboxylic acids, sulfonyl chlorides, isocyanates, and aldehydes. A hydroxyl moiety was converted to a carbamate linkage, allowing a variety of amines to be incorporated. The scaffold was anchored to TentaGel at the second hydroxyl via a succinyl linker, which was hydrolyzed by mild aqueous basic conditions. The method was used to make a library of about 17,000 different members in mixtures of 5 per sample.
