Abstract
It is shown that the cyclizations discussed proceed through twist-boat shaped carbonium ions, e.g. 9. Due to structural rigidity such a conformation cannot be assumed in a trans-fused decalin system and the reaction is arrested at the olefinic stage such as 9. The structure of ketoalcohol 9c is elucidated by X-ray crystallography.
