  Synthesis and biological activity of some very hydrophobic superagonist analogs of luteinizing hormone-releasing hormone

  摘要：

  The effect of increased hydrophobicity at position 6 of luteinizing hormone-releasing hormone (LH-RH) has been investigated by the incorporation of a series of 15 very hydrophobic, unnatural D-amino acids at this position. The unnatural amino acids studied can be considered analogues of phenylalanine with carbocyclic aromatic side chains consisting of substituted phenyl (e.g., 2,4,6-trimethylphenyl, p-biphenyl) or polycyclic aromatic (e.g., naphthalene, anthracene) units. When enzymatic resolution (subtilisin Carlsberg) of the most hydrophobic amino acids failed, the racemic amino acids were incorporated, and the diastereomeric LH-RH analogues were resolved by preparative high-performance liquid chromatography. The analogues were synthesized by the solid-phase technique. All of the synthetic compounds were very potent LH-RH superagonists, but [6-(3-(2-naphthyl)-D-alanine)]LH-RH, [6-(3-(2-naphthyl)-D-alanine), 7-(N alpha-methylleucine)]LH-RH and [6-(3-(2,4,6-trimethylphenyl)-D-alanine)]LH-RH appear to be among the most potent LH-RH agonist analogues yet reported when tested in a rat estrus cyclicity suppression assay designed to show the paradoxical antifertility effects of these compounds [ED50 approximately 7 x 10(-8) g; twice daily in saline]. These analogues are twice as potent as [D-Trp6,ProNHEt9]LH-RH in this assay system (i.e., approximately 200 times the potency of LH-RH).

  Atropos仅手性2,2'取代基的手性联苯双膦配体及其在Rh催化不对称加氢中的应用

  摘要：

  使用大体积的手性叔丁基甲基膦基嵌段，合理地设计并轻松合成了仅带有2,2'取代基的atropos手性联苯双膦配体。计算结果表明两种非对映异构体之间的自由能（7.8 kcal / mol）和从一种非对映异构体到另一种非对映异构体（27.7 kcal / mol和反向的19.9 kcal / mol）可获得的旋转能垒之间存在很大差异。该配体避免了制备轴向手性配体通常所需的费时的光学拆分，并且在Rh催化的不对称氢化反应中具有高反应活性和对映选择性。

A dramatic solvent effect was found in the hydrogenation of itaconates, which induces opposite chiralities of the product with the same catalytic system by the use of different solvents (e.g., 99.6% ee (R) in TFE
