Identification of the conformational type of seven-membered rings

  • Ideletta K. Boessenkool

A scheme for the complete characterization of seven-membered ring conformation is described. Parameters of puckering which are calculated directly from crystallographic coordinates are used to map the conformation onto a torus in relation to the various symmetrical forms.
