A long‐distance call: The inversion of configuration at a stereogenic center led to a detectable switch in the position of a 13C stereochemical probe 40 bonds (2.5 nm) away. Information was relayed between the sites by an inversion of screwsense in the intervening helix as illustrated (13C NMR signals were read as output).
长途电话:立体定向中心的构型反转导致距离40个键(2.5 nm)的13 C立体化学探针的位置出现可检测的开关。如图所示,通过插入螺旋之间的螺旋方向反转,信息在位点之间传递(将13 C NMR信号读取为输出)。
