  衍生自异恶唑盐的烯醇酯的形成，重排和水解

  摘要：

  N-叔丁基苯甲酰基酮亚胺（2c）在水中在25°[[生成酰胺（7c）]的水合反应是通过酸催化（在pH <6时）和非pH依赖的途径进行的。注意到通过乙酸的一般酸催化导致烯醇酯（3）。这些酯的进一步反应（3; R =甲基，乙基，或卜吨）在水溶液中进行了研究。在碱性溶液（pH> 6）（3; R 1 = Me或Et）经历HO - -催化的相邻的酰胺基的参与，得到Ñ酰基类似物（5），这是在随后水解成酰胺（7）速率可能比（5）的形成速率慢或快。但是，当R = Bu t时，没有O →观察到N酰基重排[即（3c）→（5c）]；取而代之的是发生缓慢的碱催化的烯醇酯水解，直接得到（7c）。在酸性溶液中，所有研究的烯醇酯都以几乎相同的速率水解。评论了这些结果对于使用异恶唑鎓盐（1）[烯醇酯的前体（3）]作为肽合成试剂的意义。

  The annulation of N-cyclopropyl enamines to produce 1,4-dihydropyridine (1,4-DHP) derivatives is described. In the presence of molecular iodine (I2), an N-cyclopropyl enamine substrate undergoes iodination, opening of the cyclopropyl ring, and annulation with a second molecule of the substrate to form the 1,4-DHP product. This reaction is amenable to gram-scale operations under mild reaction conditions

  Methods for modulating quorum sensing in certain Gram-negative bacteria having multiple QS systems including Las, Rhl, and Pqs with associated receptors (LasR, RhlR and PqsR) which are modulated by small molecule modulators, particularly non-native modulators. Certain combinations of modulators of Las, Rhl and Pqs exhibit improved inhibition of virulence in comparison to the respective individual modulators. In particular, certain combinations of modulators exhibit improved inhibition in nutritionally depleted environments. More specifically, certain combinations of modulators exhibit improved inhibition in environments depleted in phosphate and/or environments depleted in iron. Nutrient depleted environments can mimic environments associated with bacterial infection in humans and non-human animals. The methods are useful in particular for modulating QS in Pseudomonas and Buckholderia.

  在某些具有多个QS系统的革兰氏阴性细菌中，包括具有相关受体（LasR、RhlR和PqsR）的Las、Rhl和Pqs的调控方法，这些受体受小分子调节剂（尤其是非天然调节剂）的调节。Las、Rhl和Pqs的某些调节剂组合相比于各自的单个调节剂表现出对毒力的改善抑制。特别是，某些调节剂组合在营养匮乏环境中表现出改善的抑制作用。更具体地说，某些调节剂组合在缺乏磷酸盐和/或缺乏铁的环境中表现出改善的抑制作用。营养匮乏环境可以模拟与人类和非人类动物细菌感染相关的环境。这些方法特别适用于调节假单胞菌和布氏杆菌中的QS。
