Structure-function relationship of Yuehchukene II. The effect of C-6 indole rotation on anti-implantation activity

In a first attempts to define the structural requirements for the expression of anti-implantation activity in Yuehchukene (YCK), it was found that the relative position or planarity of the aromatic centres may be crucial. New synthetic routes leading to a
