β¦ Synopsis
Structure 1 proposed for isophellibilidine is confirmed by partial synthesis from the major alkaloid of Phelline billiardieri. __-_____ __-__---__--The inspection of the structures of the alkaloids present in several species of Cephalotaxus 195 and biosynthetic studies 6 show that homo-__--_-_--__erythrina alkaloids as 1 and esters of cephalotaxine 2 which possess significant antitumour activity' are probably derived from a common biogenetic precursor.
