  Kinetics of alkylhalocarbene rearrangements: modulation by fluorine substituents

  摘要：

  Rate constants were measured by laser flash photolytic methods for hydrogen and carbon 1,2-migrations in four different alkylchlorocarbenes and in the analogous alkylfluorocarbenes. The carbenes, products, and rate constants (s-1) were as follows: phenoxymethylchlorocarbene to (Z)- and (E)-1-chloro-2-phenoxyethene (Z/E approximately 4/1), k = 3.6 x 10(7); phenoxymethylfluorocarbene to (Z)-1-fluoro-2-phenoxyethene (Z/E > 10/1), k = 1.3 x 10(7); neopentylchlorocarbene to (Z)- and (E)-1-tert-butyl-2-chloroethene (Z/E = 1/12), k = 1.4 x 10(7); neopentylfluorocarbene to (Z)- and (E)-1-tert-butyl-2-fluoroethene (Z/E = 1/2.5), k = 2.6 X 10(6); cyclobutylchlorocarbene to 1-chlorocyclopentene (C migration) and chloromethylenecyclobutane (H migration), k(c) = 4.6 X 10(7), k(H) = 2.1 X 10(7); cyclobutylfluorocarbene to 1-fluorocyclopentene (C migration) and fluoromethylenecyclobutane (H migration), k(c) = 1.8 x 10(6), k(H) = 5.3 x 10(5); cyclopropylchlorocarbene to 1-chlorocyclobutene, k = 9 x 10(5); cyclopropylfluorocarbene to 1-fluorocyclobutene, k = 1.4 x 10(5). Activation energies for several of these processes were in the range of 2-4 kcal/mol, with A approximately 10(8)-10(9) s-1.

  咪唑啉受体：定性的构效关系以及曲西唑啉和苯并唑啉的发现。具有高亲和力和前所未有的选择性的两个配体。

  摘要：

  观察到所有表征咪唑啉（I）受体的尝试都是使用非选择性或选择性差的配体进行的，这促使我们进行了旨在开发选择性配体的研究。在以前的研究中，以环丙唑啉I为起点，环丙唑啉I是一种也与I受体结合的有效的α1-肾上腺素能受体激动剂，我们发现环丙基环（2）的去除保留了对I2受体的高亲和力，同时降低了α1-肾上腺素激动剂活性。但是，人们认为这种残留的α1肾上腺素激动剂活性虽然适度，但可能会降低化合物2的效用，我们现在报告我们在这一领域的不断努力。从化合物2开始，我们首先通过等位置换消除了α1-激动剂成分，然后，通过对化合物7的构象限制，成功发现了曲西唑啉（9）和苯并唑啉（12）。这两个新的配体具有高亲和力（分别为pKi值8.74和9.07），并且对alpha 2-（I2 / alpha 2 7,762和18,621）和alpha 1-（I2 / alpha 1 2,344和2,691）肾上腺素能受体具有前

  characterize imidazoline (I) receptors have been carried out with non-selective or poorly selective ligands prompted us to undertaken research aimed at developing selective ligand(s). In previous work using, as a starting point, cirazoline I, a potent alpha 1-adrenergic receptor agonist that also binds to I receptors, we showed that removal of the cyclopropyl ring (2) retains high affinity for I2 receptors
