  Synthesis of a Series of Stromelysin-Selective Thiadiazole Urea Matrix Metalloproteinase Inhibitors

  摘要：

  The synthesis and enzyme inhibition data for a series of thiadiazole urea matrix metalloproteinase (MMP) inhibitors are described. A broad screening effort was utilized to identify several thiadiazoles which were weak inhibitors of stromelysin. Optimization of the thiadiazole leads to include an alpha-amino acid side chain with variable terminal amide substituents provided a series of ureas which were moderately effective stromelysin inhibitors, with K-i's between 0.3 and 1.0 mu M. The most effective analogues utilized an L-phenylalanine as the amino acid component. In particular, unsubstituted 46 had a K-i of 710 nM, while the p-fluoro analogue 52 displayed increased potency (100 nM). Stromelysin inhibition was further improved using a pentafluorophenylalanine substituent which resulted in 70, a 14 nM inhibitor. While gelatinase inhibition was generally poor, the use of 1-(2-pyridyl)piperazine as the amide component usually provided for enhanced activity, with 71 inhibiting gelatinase with a K-i of 770 nM. The combination of this heterocycle with a p-fluorophenylalanine substituent provided the only analogue, 69, with collagenase activity (13 mu M). The SAR for analogues described within this series can be rationalized through consideration of the X-ray structure recently attained for 70 complexed to stromelysin. Uniquely, this structure showed the inhibitor to be completely orientated on the left side of the enzyme cleft. These results suggest that thiadiazole urea heterocycles which incorporate a substituted phenylalanine can provide selective inhibitors of stromelysin. Careful selection of the amide substituent can also provide for analogues with modest gelatinase inhibition.

  使用简单实用的助剂对 α-氨基酸进行配体激活的 β-C-H 芳基化

  摘要：

  在过去十年中，人们广泛探索了使用助剂作为导向基团的 Pd 催化的羧酸衍生物的 β-CH 官能化。与不对称合成中使用最广泛的助剂相比，为 CH 活化开发的助剂的简单性和实用性仍有待提高。我们之前开发了一种简单的 N-甲氧基酰胺辅助剂来指导 β-CH 活化，尽管该系统与含有 α-氢原子的羧酸不兼容。在此，我们报道了一种吡啶型配体的开发，该配体克服了 N-甲氧基酰胺助剂的这种限制，从而显着改善了羧酸衍生物，尤其是 α-氨基酸的 β-芳基化。使用这种实用助剂的芳基化应用于非天然氨基酸的克级合成，

  The use of ligands to tune the reactivity and selectivity of transition metal-catalysts for C(-sp3)-H bond functionalization is a central challenge in synthetic organic chemistry. Herein, we report a rare example of catalyst-controlled C(sp3)-H arylation using pyridine and quinoline derivatives: the former promotes exclusive monoarylation, whereas the latter activates the catalyst further to achieve diarylation. Successive application of these ligands enables the sequential diarylation of a methyl group in an alanine derivative with two different aryl iodides, affording a wide range of β-Ar-p-Ar ' -cc-amino acids with excellent levels of diastereoselectivity (d.r. > 20:1). Both configurations of the β-chiral center can be accessed by choosing the order in which the aryl groups are installed. The use of a quinoline derivative as a ligand also enables C(sp3)-H olefination of a protected alanine.

  使用配体调节过渡金属催化剂对C(-sp3)-H键官能化的反应性和选择性是合成有机化学中的一个核心挑战。在这里，我们报告了一个罕见的催化剂控制的C(sp3)-H芳基化的例子，使用吡啶和喹啉衍生物：前者促进了独特的单芳基化，而后者进一步激活了催化剂以实现二芳基化。这些配体的连续应用使得在丙氨酸衍生物中的甲基基团上进行顺序二芳基化成为可能，使用两种不同的芳基碘化物，得到了一系列具有优异立体选择性的β-Ar-p-Ar' -cc-氨基酸（d.r. > 20:1）。通过选择芳基基团的安装顺序，可以访问β-手性中心的两种构型。使用喹啉衍生物作为配体还可以实现保护丙氨酸的C(sp3)-H烯烃化。
