The chemistry of a conformationally locked tricyclo[9.3.1.03,8]pentadecane skeleton, prepared by an atropselective type 2 intramolecular Diels-Alder reaction, is examined. In many cases, the conformation of the tricycle controls the facial selectivity of the addition of nucleophilic and electrophilic reagents to this ring system.

A dependence of diastereoselectivity with steric size (van der Waals radius) of a neighboring equatorial substituent was found for both electrophilic and nucleophilic hydridereductions of the tricyclo[9.3.1.03,8]pentadecane (taxane) skeleton.
