photochemical deprotection is sufficient to refold a helical oligomer, interconverting M and P screw‐sense preference. As a consequence of the switch, information may be transmitted to a remote catalytic site, selectively directing the formation of either of two enantiomeric products by a reaction involving 1,22‐remote intermolecular asymmetric induction.
折叠器结构的细微变化可能会导致构象偏好发生重大变化。我们表明,通过改变pH值或通过光化学脱保护作用,单个氢键的简单插入或缺失就足以重新折叠螺旋低聚物,从而使M和P螺旋偏好相互转化。切换的结果是,信息可能会传输到远程催化位点,通过涉及1,22-远程分子间不对称诱导的反应选择性地指导两种对映体产物的形成。
