The reaction of L-cyanobromolycopodine with alkali proceeds with elimination of hydrogen bromide and a new ring is formed in the process, The properties of the compound, L-cyclocyanolycopodine, re­sulting from this cyclization reaction have been studied and a mechanism for its formation has been postulated. The olefin corresponding to that expected from the elimination of hydrogen bromide from L-cyanobromolycepodine has been prepared indirectly and the oxidative degra­dation of the olefin has boon investigated. / Thesis / Master of Science (MS)
