  Chemoenzymatic Dynamic Kinetic Resolution of Primary Amines Catalyzed by CAL-B at 38–40 °C

  摘要：

  The (R)-selective chemoenzymatic dynamic kinetic resolution of primary amines was performed at 38-40 degrees C in MTBE, in good to high yields and with high enantiomeric excesses. These reactions associating CAL-B to octanethiol as radical racemizing agent were carried out in the presence of methyl beta-methoxy propanoate as acyl donor, under photochemical irradiation at 350 nm in glassware.

  Thiyl Radical Mediated Racemization of Nonactivated Aliphatic Amines

  摘要：

  The racemization of nonactivated aliphatic amines has been mediated with alkanethiols and with methyl thioglycolate in the presence of AIBN. The process involves reversible H-abstraction at the chiral center, in a position R relative to nitrogen, by thiyl radical. The knowledge of the reaction enthalpy is critical to select the appropriate thiol. In the absence of experimental values, theoretical calculations of the alpha-C-H BDEs and the S-H BDE provide a useful guide.

  Optimization of the kinetic resolution of 2-amino-4-phenyl-butane was achieved at 80 °C using CAL-B-catalyzed aminolysis of carboxylic acids and their ethyl esters. The reactions carried out with long chain esters and the corresponding acids as acyl donors proceeded with remarkably high enantioselectivity. The use of carboxylic acids as acylating agents led to a marked acceleration of the reaction

  使用CAL-B催化的羧酸及其乙酯的氨解反应，可以在80°C的条件下优化2-氨基-4-苯基丁烷的动力学拆分。用长链酯和相应的酸作为酰基供体进行的反应以非常高的对映选择性进行。与它们的酯对应物相比，使用羧酸作为酰化剂导致反应速率的显着加速。月桂酸导致剩余的胺和相应的月​​桂酰胺在50％的转化率下（超过3小时）对映体过量均超过99.5％。这些优化的条件适用于一系列脂族和苄基胺的拆分。

  日期：——

  Chemoenzymatic dynamic kinetic resolution (DKR) of amines involving sulfanyl radical-induced racemization happened to be the very first switchable DKR process allowing the synthesis of either (R)- or (S)-amides, in good yield and high enantiomeric excess, depending on the nature of the enzyme; the different steps of the development of (S)-selective DKR are discussed.

  化学酶动力学分辨（DKR）中的氨胺涉及硫基自由基诱导的消旋化，恰好是首个可调节的DKR过程，能够合成（R）-或（S）-酰胺，且产率良好，对映体过量高，具体取决于酶的性质；讨论了（S）选择性DKR发展的不同步骤。

  The use of N‐octanoyldimethylglycine trifluoroethyl ester as acyl donor in the kinetic resolution of aliphatic amines catalysed by proteases led to enantiomeric ratios >200 in most cases. The resolutions mediated by Protex 6L were shown to be much faster than the resolutions achieved with the most efficient commercially available serine proteases, i.e., alkaline protease, Properase 1600L, and Subtilisin

  在大多数情况下，在蛋白酶催化的脂肪族胺的动力学拆分中，使用N-辛酰基二甲基甘氨酸三氟乙基酯作为酰基供体会导致对映体比率> 200。已证明，由Protex 6L介导的分辨率比使用最有效的市售丝氨酸蛋白酶（即碱性蛋白酶，Properase 1600L和枯草杆菌蛋白酶）获得的分辨率快得多。

  The invention relates to a purified Isometheptene compound comprising the structure according to Formula (I), (Formula (I)) or a hydrochloride, or a pharmaceutically acceptable addition salt thereof. In particular, the disclosure relates to the synthesis, purification and characterization of an Isometheptene isomer mucate crystal 2, wherein the Isometheptene isomer 2 is stereochemically characterized as (R)-enantiomer, respectively. The Isometheptene (R)-enantiomer activity indicates a selective centrally acting selective ligand for Imidazoline subtype 1 (I1) receptor sites; and more specifically, the disclosure provides an antihypertensive composition for treatment of migraine and other neurovascular or neurogenic pain from abdominal distress. (R)-Isometheptene enantiomer or isomer 2 may be an anti-hypertensive agent with lower side effects than the racemate form. Therefore (R)-Isometheptene is believed to be effective against episodic tension-type headaches (ETTH). The (R)-Isometheptene enantiomer or isomer 2 is believed to effectively lower blood pressure, used alone or together with other headache ameliorating drugs. Methods of synthesis and treatment are described. Regarding (R)- Isometheptene crystals data of X-ray crystallography are presented.
