Abstract
One of the largest subfamilies within the famous Daphniphyllum alkaloid family is made up of the yuzurimine-type(or macrodaphniphyllamine-type)alkaloids.Their complex aza-polycyclic caged struc-tures,several contiguous stereogenic centers,and vicinal all-carbon quaternary centers make these al-kaloids formidable challenge for synthetic chemists.Recently,synthesis of these alkaloids has received extensive attention from our community.Herein,we wish to report the total synthesis of C14-epi-deoxycalyciphylline H,a putative member of yuzurimine-type alkaloid subfamily.Key transformations employed in our approach include an intramolecular Prins reaction and a Pd-catalyzed enyne cycloiso-merization.In addition,synthesis of a daphnezomine L-type alkaloid,paxdaphnidine A,was also studied.
