Abstract
The conformational behaviour of 6βalkylβ3βoxoβ2βoxabicyclo[3.3.0]octanβ7βols and some derivatives possessing the configurations a (6βendoβ7βexo), b (6βendoβ7βendo) and c (6βexoβ7βendo) is discussed. It is shown that an easy configurational assignment is possible between these three series.
