A novel linker for solid phase synthesis is described, which exhibits rapid cleavage under selective, orthogonal conditions, including stability under acidic conditions. The linker incorporates a pyridyl propionate system, with a pendant β-silyl group. Rapid cleavage of the product is effected by elimination of the silyl group on treatment with fluoride. Two systems of this type have been synthesised
描述了用于固相合成的新型接头,其在选择性的正交条件下表现出快速裂解,包括在酸性条件下的稳定性。连接子结合了带有吡啶基β-甲硅烷基的丙酸吡啶基酯系统。通过用氟化物处理除去甲硅烷基,可以实现产物的快速裂解。已经合成了两种类型的这种系统,并且已经在酸性和碱性条件下在溶液中测试了接头的稳定性。
