A novel endocyclic enamine cyclopentenone annulation was discovered and rationalized as an unusual Nazarov-type electrocyclization, which would have broad applications in the synthesis of natural alkaloids and other heterocycles.

我们在合成路线一、路线二中用的6-6元环系到7-5元环系的还原重排反应，在温和的酸性还原条件下即能发生，这说明在三尖杉碱的生物合成中6-6元环到7-5元环的还原重排步骤是非常有可能发生的；因此，我们的合成路线二中可认为是生物合成过程。

Study on the rapid Propagation Technique of Lycoris. Herb and get follow results: In the period found of axenic clone 0.1%HgCl2 is the best disinfector to deal with the Lycoris" bulb ,as to neat part, such as root, leave, and bulbil, is fit to use 0.1%HgCl2 antisepsis 7min. And found the best effect is the bulb scale with base. Root, leaf and bulb scale without base all were not inducement adventitious buds. Different position of bulb had different culture effect. 3-15 of middle part of bulb can be induced most adventitious buds but inner and outer of least it. Incised the bulb with three types (pieces of eight, pieces of six, piece of four), and found the type of pieces of six is best to Lycoris mass production. L.sprengeri is fit MS+BA5mg/l+NAA0.1mg/l and L.squamigera is fit MS+BA5mg/l+NAA0.5mg/l, but the medium fit to culture L.longituba haven"t be found.In the period of Subculture-Found of mass production, the most multiplication of adventitious buds in MS+BA5mg/l+NAA0.5mg/l during subculture of L.sprengeri, L.squamigera.

石蒜属植物快速繁殖技术研究中，在无菌无性系建立阶段：鳞茎以0.1％HgCl_2消毒10-12分钟效果最好，而叶、根尖、鳞芽等较干净部位选用0.1％HgCl_2消毒7分钟；用三种石蒜属植物的叶片、根尖、鳞芽及带基盘与不带基盘鳞片进行培养，以带基盘鳞片诱导分化效果最理想，鳞芽易培养出芽，但数量有限，而叶片、根尖与不带基盘鳞片均未诱导分化；带基盘鳞片为石蒜属植物快速繁殖最佳外植体，以鳞茎中部3-15层芽诱导率高，较外层稍次之，内部鳞片诱导率最低；选用八等分法、六等分法、四等分法切割鳞茎，六等分法综合效果最好；每外植体带三鳞片培养最为适宜；三种石蒜属植物各自适合的培养基成分不同，换锦花在MS+BA5mg／l+NAA0.1mg／l中培养效果最好，夏水仙为MS+BA5mg／l+NAA0.5mg／l，而白花长筒石蒜在各培养基组合中培养效果均不理想，其适合的培养条件有待于进一步研究。

She thought of the child consigned to the nethermost corner of hell, as its double doom for lack of baptism and lack of legitimacy; saw the arch-fiend tossing it with his three-pronged fork, like the one they used for heating the oven on baking days; to which picture she added many other quaint and curious details of torment sometimes taught the young in this Christian country.

她想到了那孩子，既是私生，又未受洗，两罪俱罚，就会打到地狱最底层的犄角。她仿佛看见魔王正拿着一把三尖叉，就像人们烤面包时加热炉灶用的那种，把那孩子叉住抛来扔去；在这想像的画面中，她又增添了许多这个基督教国家有时向年轻人昭示的种种稀奇古怪的酷刑。
