Birman's synthesis of sceptrin

Background

        Sceptrin is a useful naturally occurring product. found Agelas sceptrum, which is a sponge that inhabits the Glover Reef in Belize. The chemical has anti-bacterial, antiviral, and anti-histaminic properties. Sceptrin also has anti-muscarinic properties. The term muscarinic is derived from Muscarine, which is an alkaloid poison found in certain fungi.
