described. In addition, features relative to library construction, such as the chemoselective nature of dipole formation, are discussed. Through the investigation of the temperature sensitive cleavage step, the furan synthesis was found to be accelerated by aqueous medium at physiological temperature leading to pure product from the solid-phase under biologically relevant conditions. The chemoselective
描述了用于选择性形成基于呋喃的模板指导的支架的一般环加成-环还原复分解程序。另外,还讨论了与文库构建有关的特征,例如偶极形成的化学选择性。通过对温度敏感裂解步骤的研究,发现呋喃的合成在生理温度下被水性介质加速,从而在生物学相关条件下从固相得到纯产物。铑(II)介导的环加成反应的化学选择性使得在存在许多碳烯活性官能团的情况下选择性地形成关键的偶极中间体,从而有助于小化合物库的拆分池组合合成。
