Trans-Decahn

Decahn ring systems appear as structural units m a large number of naturally occur ring substances particularly the steroids Cholic acid for example a steroid present m bile that promotes digestion incorporates as decahn and trans decahn units into a rather complex tetracyclic structure... [Pg.131]

In each compound, the A-B fusion represents a trans-decahn system ... [Pg.128]

Two cyclohexane rings can be joined in either a cis or a trans manner. With cis fusion to give cis-decahn, both groups at the ring-junction positions... [Pg.965]

An isomerization equilibrium between ar-decahn and rm r-decalin can be estabhshed by heating the mixmre to about 300 °C in the presence of a palladium catalyst. The trans isomer predominates. Why is the trans isomer more stable than the cis isomer ... [Pg.161]
