  摘要：

  3-氨基氨基甲基-（8），3-咪唑啉基甲基-（9）和3-四氢吡啶基甲基-1, 2-苯异噁唑（10）是通过亚胺醚（7）从1, 2-苯异噁唑-3-乙腈（4）合成的。3-四唑基甲基-1, 2-苯异噁唑（5）和1, 2-苯异噁唑-3-乙酰胺肟（11）也由4合成。3-氨基乙基-1, 2-苯异噁唑（25），是1, 2-苯异噁唑的色氨酸类似物，是通过3-氯乙基-1, 2-苯异噁唑（20）合成的。1, 2-苯异噁唑-3-乙酸（1）与等量的溴进行溴化反应生成α-溴-1, 2-苯异噁唑-3-乙酸（27），后者去羧化得到3-溴甲基-1, 2-苯异噁唑（30）。将30进行氨基化得到3-氨基甲基-1, 2-苯异噁唑（31）。用过量溴对1进行溴化反应生成3-三溴甲基-1, 2-苯异噁唑（28）。N-取代的1, 2-苯异噁唑基甘氨酸酯（32）是通过溴化甲基-1, 2-苯异噁唑-3-乙酸酯（29）合成的，后者是通过对甲基-1, 2-苯异噁唑-3-乙酸酯（2）进行溴化获得的。

  This invention provides methods whereby taxol, baccatin III, and other taxol-like compounds, or taxanes, can be produced in very high yield from all known Taxus species, e.g. brevifolia, canadensis, cuspidata, baccata, globosa, floridana, wallichiana, media and chinensis. Particular modifications of culture conditions (i.e. media composition and operating modes) have been discovered to enhance the yield of various taxanes from cell culture of all species of Taxus. Particularly preferred enhancement agents include silver ion or complex, jasmonic acid (especially the methyl ester), auxin-related growth regulators, and inhibitors of the phenylpropanoid pathway, such as 3,4-methylenedioxy-6-nitrocinnamic acid. These enhancement agents may be used alone or in combination with one another or other yield-enhancing conditions. While the yield of taxanes from plant cell culture of T. chinensis is particularly enhanced by use of one or more of these conditions, yield of taxanes for all Taxus species has been found to benefit from use of these conditions.

  本发明提供了可从所有已知的紫杉品种（如brevifolia、canadensis、cuspidata、baccata、globosa、floridana、wallichiana、media和chinensis）中以极高产率生产紫杉醇、巴卡丁Ⅲ和其他紫杉醇类化合物或紫杉素的方法。已发现对培养条件（即培养基成分和操作模式）的特定修改可提高所有紫杉属植物细胞培养中各种紫杉素的产量。特别优选的增强剂包括银离子或银离子络合物、茉莉酸（尤其是甲酯）、与辅助素相关的生长调节剂和苯丙醇途径抑制剂，如 3,4-亚甲二氧基-6-硝基肉桂酸。这些增产剂可以单独使用，也可以相互结合或在其他增产条件下使用。虽然使用其中一种或多种条件可特别提高植物细胞培养 T. chinensis 的紫杉醇产量，但已发现使用这些条件可提高所有紫杉属植物的紫杉醇产量。
