A chiral non-nucleosidic phosphoramidite building block containing a thioester function in its structure, 4, is synthesized in six steps starting from ‘2-deoxy-D-ribose’. It is used in the machine-assisted oligonucleotide synthesis in a conventional manner. Upon completion of the oligonucleotide chain assembly the thioester bond is cleaved with various nucleophiles (hydroxide ion, propane-1,3-diamine, cystamine, histamine), resulting in oligonucleotide conjugates with a tether group in the middle of the oligonucleotide chain.
从 "2-脱氧-D-核糖 "开始,通过六个步骤合成了一种手性非核苷磷酸酰胺结构单元 4。它以传统方式用于机器辅助寡核苷酸合成。寡核苷酸链组装完成后,硫酯键会被各种亲核剂(氢氧根离子、丙烷-1,3-二胺、胱胺素、组胺)裂解,从而产生在寡核苷酸链中间带有一个系基的寡核苷酸共轭物。
