Two new dibenz[d,f]azonine alkaloids, neodihydrothebaine and bractazonine were isolated from Papaver bracteatum. Their possible biosynthesis from thebaine is discussed. The structures of both new alkaloids are proven by synthesis. An isomeric dibenz[d,f]azonine compound was also prepared.
从罂粟中分离出两种新的二苯并[d,f] azonine 生物碱neodihydrothebaine 和bractazonine。讨论了它们可能从蒂巴因生物合成。两种新生物碱的结构均通过合成证明。还制备了异构二苯并[d,f]氮杂化合物。
