Abstract: The present invention relates to a method by which saccharide compounds can be prepared in a very easy way. This method comprises the steps of: (a) attaching at least one saccharide to a cyclic or acyclic diene, (b) reacting the saccharide-containing diene obtained in step (a) or a commercially available saccharide-containing diene with a dienophile by Diels-Alder reaction.

Abstract: An enzyme cleavable linker is prepared on which organic compounds are synthesized when the linker is bound to a solid phase. The linker contains a functional group on which a synthesized organic compound is bound when synthesis takes place, and a recognition site for a hydrolytic enzyme. Reacting the linker with the enzyme causes the linker to fragment at a site different from the recognition site to liberate the synthesized organic compound. The solid phase may be a crosslinked polyacrylamide containing an amino group for attaching the linker, and the linker is bound to the solid phase via a spacer. The spacer is attached to the solid phase by an ester, ether, amide or amine linkage, or a sulfide or phosphate linkage. In a specific reaction of forming a solid phase containing the linker, 2-acetoxy-5-hydroxymethylbenzoic acid is attached to an amino group-containing polymer via a spacer followed by conversion to a chloroformic ester.
