    • 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.
    • 制备可切割接头的酶切割接头,当接头与固相结合时,合成有机化合物。 接头含有合成有机化合物结合的官能团,以及水解酶的识别位点。 用酶使接头反应导致接头在不同于识别位点的位点断裂,以释放合成的有机化合物。 固相可以是含有用于连接接头的氨基的交联聚丙烯酰胺,并且接头通过间隔物与固相结合。 间隔物通过酯,醚,酰胺或胺键或硫化物或磷酸酯键与固相相连。 在形成含有连接体的固相的具体反应中,将2-乙酰氧基-5-羟甲基苯甲酸经由间隔物连接到含氨基的聚合物上,然后转化为氯甲酸酯。
