  氮杂spiroaminal的简易仿生合成

  摘要：

  氮杂螺旋体天然产物显示出一个常见的含有螺旋体的末端结构域，该结构域启发了两种新的螺旋体合成方法的开发-Staudinger还原-aza-Wittig过程和双分子内异Michael加成。这些有效的实验室方法通过亚胺和烯胺中间体进行，这些中间体可能反映了短暂的生物遗传物种。

  Antibodies with Broad Specificity to Azaspiracids by Use of Synthetic Haptens

  摘要：

  The development of general, sensitive, portable, and quantitative assays for the azaspiracid (AZA) class of marine toxins is urgently needed. Use of a synthetic hapten containing rings F-I of AZA to generate antibodies that cross-react with the AZAs via their common C28-C40 domain and use of these antibodies in ELISA and immunoaffinity columns are reported. This approach has many advantages over using intact azaspiracids (AZAs) derived from environmental samples or total synthesis as haptens for antibody development. A derivative of the levorotatory C28-C40 azaspiracid domain (1) was synthesized efficiently using a one-pot Staudinger reduction/intramolecular aza-Wittig reaction-imine capture sequence to form the H-I ring spiroaminal and a double intramolecluar hetero-Michael addition to assemble the F-G ring ketal. Conjugation of the hapten 1 to cBSA and immunization in sheep generated antibodies that recognized and bound to ovalbumin-conjugated 1 in the absence of AZA1. This binding was inhibited by 1 in a concentration-dependent manner. A mixture of AZA1, AZA2, AZA3, and AZA6 caused a degree of inhibition of antibody binding consistent with its total AZA content, rather than just its content of AZA1. This result suggests that the antibodies also have a similar affinity for AZA2, AZA3, and AZA6 as they do for AZA1 and that such antibodies are suitable for analysis of AZAs in shellfish samples.

• Facile biomimetic syntheses of the azaspiracid spiroaminal

  The azaspiracid natural products display a common spiroaminal-containing terminal domain that has inspired the development of two new methods for spiroaminal syntheses—a Staudinger reduction–aza-Wittig process and a double intramolecular hetero-Michael addition. These effective laboratory approaches proceed through imine and enamine intermediates that may reflect transient biogenetic species.
