A long‐distance call : The inversion of configuration at a stereogenic center led to a detectable switch in the position of a 13 C stereochemical probe 40 bonds (2.5 nm) away. Information was relayed between the sites by an inversion of screw sense in the intervening helix as illustrated ( 13 C NMR signals were read as output).
