The rapidly expanding field of combinatorial chemistry has stimulated the development of new methods and synthetic strategies for assembly of compound libraries. We propose four criteria that are desirable for synthetic routes to such libraries: (1) the sequence involves a small number of steps; (2) no more than one variable is introduced in any step; (3) starting materials are readily obtained with

A polygonal scaffold includes at least three polyproline II (PPII) helix rods and at least three connectors. Each of the PPII helix rods is composed of a plurality of repeat units represented by Formula (i), and at least one of the PPII helix rods has at least one of hydrogen atoms of at least one of the repeat units being substituted by a first chemical handle for connecting a ligand. Each of the connectors is a divalent organic group, and every two of the PPII helix rods are connected by one of the connectors to form a closed ring.

Each of the PPII helix rods is composed of a plurality of repeat units represented by Formula (i), and at least one of the PPII helix rods has at least one hydrogen atom of at least one of the repeat units being substituted by a first chemical handle for connecting a ligand. Each of the connectors is a divalent organic group, and every two of the PPII helix rods are connected by one of the connectors to form a closed ring. Therefore, with the uniform composition, the PPII helix rods have a stable helical structure under aqueous conditions, and a desired rigidity can be provided.

A wide range of chiral mono- and ditopic cyclodextrin-based receptors have been synthesized by CuI-catalyzed azide-alkyne cycloaddition starting from mono-6-azido-beta-cyclodextrin and chiral amino acids. Of interest, microwaves proved very efficient to access a wide range of ditopic beta-cyclodextrin receptors with quantitative yields.
