Snakes and ladders. The sigmatropic shiftamer concept.
Sigmatropic shiftamers are organic molecules (conceived originally as polymers) in which bonds migrate back and forth along their frameworks. In this Account, we describe the origins of the sigmatropic shiftamer concept, theoretical predictions of molecular architectures that may support shiftamer behavior, and possible future directions for research on this class of molecules.
