A mild and versatile method based on Cu(I)-catalyzed [3+2] cycloaddition (Meldal-Sharpless reaction) was developed to tether biomolecules, such as monosacharides or lipophylic azides, to alkyne functions of spirobenzo[b]thieno[2,3-d]pyrimidine-1´-cyclohexane. The reactions are highlighted by their modularity and high efficiency with excellent yields in most cases. The products are interesting precursors for a variety of applications.
我们开发了一种基于 Cu(I)-catalyzed [3+2] cycloaddition(Meldal-Sharpless 反应)的温和而多用途的方法,用于将生物大分子(例如单沙酰胺或脂族叠氮化物)拴系到螺苯并[b]噻吩并[2,3-d]嘧啶-1´-环己烷的炔官能团上。这些反应具有模块化和高效的特点,在大多数情况下产量极高。这些产物是多种应用的有趣前体。
