Gezielte Konformationsänderungen an cyclischen Systemen, 1. Mitt.: Das Isokonformationskonzept

By means of the “isoconformational concept” it is shown that a correlation of conformations of ring compounds with the corresponding patern of signs for their torsional angles and an equal number of torsional degrees of freedom is feasible, as far as geometrically required conformational changes are concerned (i.e. disregarding secondary, system inherent effects). The applicability of the concept is studied by means of 1- and 1,10-substituted [2.2]metacyclophanes, the conformations of which can be deduced from the “geometric behaviour” of cyclohexane.
