A procedure for using thermolabile groups to protect a hydroxyl function, above all in nucleosides, nucleotides, oligomers, nucleic acids during the reactions of organic synthesis. Various new compounds that can be used to implement the procedure. The way of using thermolabile groups to protect hydroxyl functions consists in a primary, secondary and tertiary hydroxyl group converting into a groups during the reaction between a compound and a compound whose hydroxyl group is to be blocked. The blocking reaction is carried out by means of widely known methods appropriate for that purpose in the presence of a chemically basic catalyst. The obtained product has its hydroxyl group blocked. Then the compound with the group blocked can be used for the purposes of various chemical processes. After their completion, the hydroxyl group is unblocked by dissolving it in a solvent at a temperature of 50-95° C.
使用热敏基团保护羟基官能团的方法,尤其适用于核苷、核苷酸、寡聚物和核酸在有机合成反应中的保护。还提供了多种新化合物可用于实施该方法。使用热敏基团保护羟基官能团的方法是将一次、二次和三次羟基官能团转化为基团,然后在化合物与需要被阻断羟基官能团的化合物之间的反应中进行。阻断反应在
化学碱催化剂的存在下进行,采用广泛已知的适用于该目的的方法。得到的产物具有其羟基官能团被阻断的特点。然后,带有阻断基团的化合物可以用于各种
化学过程。在完成这些过程后,可以通过在50-95°C的溶剂中溶解来解除羟基官能团的阻断。
