| 摘要 |
A substrate for solid phase synthesis comprising a solid phase-linker combination of the formula I is disclosed. Also disclosed are processes for preparing the substrate and chemical intermediates useful therein. Among the novel intermediates are compounds of the formula II wherein R1 is -NO2 or -CHO; R2 is -OCH3, -CHO or -H; R3 is chosen from the group consisting of hydroxyl, the residue of a solid support having a plurality of amino groups, and the residue of an ester, and n=1 or 3.A substrate of solid phase synthesis of the formula III is also disclosed. |
