Subsequently, a new thiolactone can be reinstated by means of an α-isocyanato-γ-thiolactone. Different acrylic compounds were used to incorporate diverse functionalities in the oligomers, which were built up to the level of decamers. The reaction conditions were closely monitored in order to fine-tune the applied strategy as well as facilitate the translation to an automated protocol.
基于含有
异氰酸酯和
硫代内酯的易于获得的分子的固有反应性,通过无保护基团的两步迭代方案在固体支持物上获得了长的、多功能序列定义的寡聚物。后者实体与
氨基醇的
氨解释放出
硫醇,该
硫醇与存在于相同介质中的
丙烯酸酯或
丙烯酰胺反应。随后,可以通过 α-异
氰酸根合-γ-
硫内酯恢复新的
硫内酯。不同的
丙烯酸化合物被用来在低聚物中加入不同的官能团,这些功能达到了十聚体的
水平。密切监测反应条件,以微调应用的策略并促进向自动化方案的转化。
