✦ Synopsis

In Previous reports' from these laboratories an efficient route to the pentacyclic diether 1 was described. A pentacyclic diaromatic compound of this type, with the trans-anti-trans BCD ring structure and the correct array of angular methyl groups, was envisaged as a useful key intermediate for the total synthesis of pentacyclic triterpenes of the friedelin (2)' structural
