  取代的反式-4-氨基-3,4-二氢-2,2-二甲基-2H-1-苯并吡喃-3-醇的合成及降压活性。

  摘要：

  制备了一系列新型取代的反式-4-氨基-3,4-二氢-2,2-二甲基-2H-1-苯并吡喃-3-醇，并在有意识的乙酸脱氧皮质酮（DOCA）/盐水处理中测试了其降压活性。高血压大鼠。最佳的降血压活性需要一个强的吸电子基团与6位上的吡咯烷基或哌啶子基团一起进行6位取代。7-硝基-4-吡咯烷类似物和6-硝基-3-氯丙胺的例外，它们保留了明显的降压活性。所有这些化合物都是直接的血管扩张药，并且具有与肼屈嗪和钙拮抗剂硝苯地平相当的降压活性。这些化合物的合成路线包括将炔丙基醚环化为2H-1-苯并吡喃，然后通过溴代醇转化为3,4-环氧化物，用适当的胺开环。间取代的炔丙基醚在热环化反应中同时产生5-和7-取代的苯并吡喃，前者占优势。描述了一种新的制备2，2-二甲基-7-硝基苯并吡喃的途径。

  基于特权结构的类天然产物组合库。1. 苯并吡喃的一般原理及固相合成

  摘要：

  在此，我们报告了一种基于特权结构原理设计和构建天然和天然产物类库的新策略，该术语最初用于描述能够与各种不相关的分子靶标相互作用的结构基序。讨论了天然产物中此类特权结构的鉴定，随后选择 2,2-二甲基苯并吡喃部分作为通过该策略构建类天然产物库的初始模板。最初，采用独特的环加载策略开发了苯并吡喃基序的新型固相合成，该策略依赖于使用新的聚苯乙烯基溴化硒树脂。一旦确定了这些苯并吡喃的加载、加工和裂解，

  A mild and efficient copper‐catalyzed intramolecular carbotrifluoromethylation of alkynes has been achieved in the presence of Togni reagent as trifluoromethylating reagent. The reaction tolerates a range of substrates to give a group of trifluoromethylated heterocycles with high selectivities. A plausible mechanism was proposed on the basis of experimental results.

• Synthesis and Structure−Phytotoxicity Relationships of Acetylenic Phenols and Chromene Metabolites, and Their Analogues, from the Grapevine Pathogen <i>Eutypa </i><i>l</i><i>ata</i>

  Eutypa lata, the fungus responsible for dying-arm disease in grapevines, produces a number of structurally related secondary metabolites, of which eutypine (1) has been implicated as the principal phytotoxin. However, analysis of an E. lata strain from California known to be pathogenic to grapevines showed that eutypine was not present, suggesting that other metabolites could be phytotoxic. Investigation of the relative phytotoxicities of individual metabolites has been limited by insufficient material and lack of a reliable bioassay. Metabolites of particular interest and their precursors were therefore synthesized, and a rapid, quantitative bioassay via topical application of individual compounds to disks of grape leaves and measurement of chlorophyll loss was developed to provide a relative measure of tissue damage. The recently reported metabolite eulatachromene (2) was found to have phytotoxicity greater than that of eutypine (1). The cyclization product, 5-formyl-2-methylvinyl[1]benzofuran (3), also showed significant activity, whereas the reduction product, eutypinol (4), was inactive, as was the quinol, siccayne (5). These results indicate that before strains of Eutypa are incriminated as pathogenic they must be analyzed for the presence or absence of specific constituents for which the phytotoxicity has been unequivocally established.
